MMX TM Technology
The MMX TM Technology extension to the Intel Architecture is designed to accelerate multimedia and communications software running on Intel Architecture processors (Peleg and Weiser). The technology introduces new data types and instructions that implement a SIMD architecture model and is defined in a way that maintains full compatibility with all existing Intel Architecture processors, operating systems, and applications. MMX technology on average delivers 1.5 to 2 times performance gains for multimedia and communications applications in comparison to running on the same processor but without using MMX technology. This extension is the most significant addition to the Intel Architecture since the Intel I386 and will be implemented on proliferation of the Pentium processor family and also appear on future Intel Architecture processors.
The media extensions for the Intel Architecture (IA) were designed to enhance performance of advanced media and communication applications. The MMX™ technology provides a new level of performance to computer platforms by adding new instructions and defining new 64-bit data types, while preserving compatibility with software and operating systems developed for the Intel Architecture.
The MMX technology introduces new general-purpose instructions. These instructions operate in parallel on multiple data elements packed into 64-bit quantities. They perform arithmetic and logical operations on the different data types. These instructions accelerate the performance of applications with compute-intensive algorithms that perform localized, recurring operations on small native data. This includes applications such as motion video, combined graphics with video, image processing, audio synthesis, speech synthesis and compression, telephony, video conferencing, 2D graphics, and 3D graphics
The MMX instruction set has a simple and flexible software model with no new mode or operating-system visible state. The MMX instruction set is fully compatible with all Intel Architecture microprocessors. All existing software continues to run correctly, without modification, on microprocessors that incorporate the MMX technology, as well as in the presence of existing and new applications that incorporate this technology.
MMX technology provides the following new features, while maintaining backward compatibility with all existing Intel Architecture microprocessors, IA applications, and operating systems; New data types, eight MMX registers, enhanced instruction set. The performance of applications which use these new features of MMX technology can be exchanged.
The principal data type of the IA MMX technology is the packed fixed-point integer. The decimal point of the fixed-point values is implicit and is left for the user to control for maximum flexibility.
According to Penner et al. (2013), there are various causes of healthcare disparities, such as socioeconomic status; this results to poor healthcare services for people with low socioeconomic status, as people with low pay find it difficult to leave their work to seek healthcare help, or to afford healthcare insurance (p.4). The second cause is language proficiency. The language barriers faced by the immigrant plays a role in the healthcare disparities among the racial or ethnic minority patients. Another cause is health literacy. The levels of the health literacy among the foreign born individuals can be influenced by their higher level of distrust of the healthcare providers and healthcare system than they have towards Caucasian people. This, in turn, leads them to seek healthcare information less often than their Caucasian counterparts, thus hindering the provision of quality services, as well as limiting the foreign patients’ ability to manage their health conditions effectively. The foreigners’ failure to easily accept the information provided to them by healthcare providers puts them at risk. Disentangling the role of health literacy in racial healthcare disparities from the effects of racial attitudes and beliefs is often hard (Penner et al,
The endocrine system consists of six parts; pancreas hypothalamus, thyroid, pituitary gland, ovary, and adrenal gland. The pancreas is a large gland that produces hormones that regulate blood sugar; produces enzymes that break down carbohydrates, lipids, proteins, and nucleic acids; and produces sodium bicarbonate, a base that neutralizes stomach acid. The hypothalamus is a brain structure that acts as a control center for recognition and analysis of hunger, thirst, fatigue, anger, and body temperature. The thyroid is a large gland in the neck that secretes (produces) hormones regulating growth through the rate of metabolism. The pituitary gland is in the base of the skull that secretes nine hormones that directly regulate many body functions and control the actions of several other endocrine glands. The ovary ( found in females) is a gonad that produces eggs. The adrenal glands are a pair of glands located above the kidneys, which produces epinephrine and norepinephrine. The endocrine system main function is to release hormones that affect activities of other cells.
Today there are huge enhancements in the diagnosis and treatment of most chronic diseases, there are many studies shown that ethnic and racial minorities obtain lower health care than nonminorities.
Health disparities are different because they are based upon creating resolutions to better serve the needs of the population and environment. A health disparities helps to revolutionize the growth of medicine and public health. It the study of what lacks and measurement of improvements.
Health disparities are the variances in access to healthcare. This also include variance in availability of health care services, facilities, education, and insurance. Another aspect is the variance in the type of violence, injury, and disease that exist in specific communities and ethnic groups. Health disparities leads to inequalities in healthcare access and availability. Health disparities could have negative effects on the health of groups of people, resulting from greater social and economic obstacles. These obstacles could come from discrimination/exclusion due to ethnicity, religion, socioeconomic status, gender, sexual orientation, and geographic location.
Data Encryption is from the cryptography science, which includes coding and decoding of message to protect the safety. Development computer technology makes the encryption even more complicated. The ability for people to break codes is increasing, so are the ability to guard the codes. Many encryptions are available now. They were developed by some hi-tech company and sold, or you can choose some free service. Actually, when you are using the web browsers, emails, or even the basic system, your information has been automatically encrypted.
Public key encryption is one type of cryptographic mechanism that uses asymmetric key pair to encrypt and decrypt the message which means the key used to encrypt the message differs from the key used to decrypt one. It was first published by Whitfield Diffie and Martin Hellman in the year 1976. A public-key encryption includes six main elements which are as follows-
Specifically, volunteering can combat and help aid in the treatment of mental disorders. To emphasize, volunteering has been found to significantly lower levels of depression (Dietz et al.). When a person focuses on others it is easier to forget our own personal struggles and lower mental disorders. In addition, it creates a sense of purpose in the world. To demonstrate, the “social integration theory” or “role theory” provide an explanation that people involved in community service feel more life satisfaction and purpose (Dietz et al.). Having a sense of belonging and purpose helps overall psychological well being. Lastly, volunteering increases self-confidence. For instance, volunteering is attached to a “natural sense of accomplishment” (Segal and Robinson). Thus, volunteerism has a strong connection to an increase in confidence and self-discovery. Overall, volunteerism increases a person’s mental state of mind in many ways, but also
Then came Linus Benedict Torvalds. At the time he was a sophomore majoring in Computer Science at the University of Helsinki, his hobby also included computer programming. At 21 he found himself spending most of his time toying with computer systems, trying to see what he could do in order to push their limits and increase their functionality. The key missing in his tests was an operating system that had the flexibility craved for by professionals. MINIX was available, though it was still just a stu...
The computer processor is the brain of the system. Our client requires a heavy punch, multi tasking brain. Due to his low income and student status, he does not have a large budget to put towards his computer. The AMD AthlonXP 1900 was chosen because of it's low cost and it's higher performance rating than that of the higher priced equivalent Pentium 4. The AMD AthlonXP 1900's speed is 1.6GHz. This means 1600Hz, which is a very fast processor. Amazingly, the clock speed of this processor is faster, albeit barely, than the Pentium 4 2.0GHz processor, and is much cheaper as well. This is important, as, for less cash, our student can afford a better processor.
Volunteering enables an individual to make a positive impact on his or her community, while empowering the individual to better his or her life. This summer, I had the opportunity to volunteer at many diverse locations. From the hospital to the local library, I truly value my experience and treasure everything it has thought me. Volunteering lets us experience and learn things that we otherwise would not have learned; volunteering opens doors for us that we may not have been able to open before. Volunteering provides us with guidance and tolerance which we may use in the future to aid us in our decisions. At first glance, volunteering may seem to only benefit those who are helped, but on a deeper level, one can realize that volunteering benefits the volunteer as much as, if not more than, those who are helped. Not only does volunteering make a difference in one’s community, but it also helps the volunteer become a smarter, happier, friendlier and more caring individual.
Each gland of the endocrine system is responsible for the releasing of different hormones, and those hormones trigger different activities in different places of the body. Hypothalamus, pineal body, anterior and posterior pituitary glands, adrenal gland, and thyroid gland are the main glands of the endocrine system while there are some other associated glands, as well. The endocrine system is known to be as the chemical information system. Some of the main functions of this system have to do with growth and development, metabolism, tissue function, sexual function, mood swings,
Hypothalamus – The hypothalamus is located in the brain. It is responsible for direct control over the entire endocrine system through the pituitary gland. Cells in the hypothalamus called neurosecretory cells secrete 7 hormones – Thyrotropin-releasing hormone (TRH), Growth hormone-releasing hormone (GHRH), Growth hormone-inhibiting hormone (GHIH), Gonadotropin-releasing hormone (GnRh), corticotropin-releasing hormone (CRH), oxytocin and Antidiuretic hormone (ADH).
There are three major glands in the endocrine system, which are the thyroid gland, adrenal glands, the ovary and testes, and the pituitary gland. A section of the brain above the pituitary gland called the hypothalamus controls the endocrine system and communicates with...
