MMX Technology :: essays research papers fc

MMX TM Technology The MMX TM Technology extension to the Intel computer computer architecture is intentional to accelerate multimedia and communications software rill on Intel architecture processors (Peleg and Weiser). The technology introduces revolutionary data types and book of instructions that implement a SIMD architecture model and is defined in a way that maintains full compatibility with all told actual Intel Architecture processors, operating systems, and applications. MMX technology on average delivers 1.5 to 2 times implementation gains for multimedia and communications applications in comparison to running on the same processor but without using MMX technology. This extension is the most(prenominal) signifi flush toilett 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 d esigned 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 real for the Intel Architecture. The MMX technology introduces new general-purpose instructions. These instructions operate in parallel of latitude on multiple data elements packed into 64-bit quantities. They perform arithmetic and licit 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(prenominal) as motion video, combined graphics with video, image processing, audio synthesis, rescue synthesis and compression, telephony, video conferencing, 2D graphics, and 3D graphics The MMX instruction set out has a simple a nd flexible software model with no new mode or operating-system visible state. The MMX instruction set is fully harmonious 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 inverse 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 ten-fold point of the fixed-point values is implicit and is left for the user to control for maximum flexibility.
