According to foreign reports, AMD requires developers to consider how they use the new instructions to improve the speed of its software. These new instructions will appear in AMD in 2009 introduced a new processor.
These new instructions will simplify developers to write for the image block, photos and increased color space audio effects such as double counting code method.
Bulldozer code based on AMD 64 位 future x86 processors will understand the extended instruction set. AMD to the instruction set known as SSE5. AMD on Thursday (August 30) released a notice, the developers introduced SSE5 specification.
Each new instruction will use a certain part of the instruction processing of data. This feature is called "SIMD" (single instruction, multiple data). In 1999, Intel x86 instruction set to increase in the first SSE (single instruction multiple data extension) instructions, and since then several generations of increased instruction set. Intel released in April this year, the latest SSE4 programming reference.
AMD processors support Intel in its instruction set extensions are generally behind with Intel. AMD hopes to launch SSE5 instruction set for developers and software buyers have extra reason to choose AMD processors instead of Intel's products.
SSE5 instruction set to speed up the implementation of the single speed increase, said 47 new basic instructions. A kind known as "multiply-add-accumulate" (multiply total) in order to allow developers to operate the cumulative number of double counting the same results, do not directly increase, respectively, resulting in improved image rendering, or used to create 3D sound effects calculation speed. Another command that allows developers to multiply the contents of two registers, the results are stored in registers in the third. This 3 instruction computing can save developers a number of registers in the data processing time.
However, if the software buyers from these instructions to get the benefits of increased performance, developers need to optimize the code editor and other software tools to use these instructions. Now published by SSE5 instruction set specification, AMD hopes in 2009, before the launch of the first Bulldozer chip tool manufacturers to work with some editors need to use some of the information.
