* Project: vector classes
|
||
|
|
* Description:
|
||
|
|
* Header file defining vector classes as interface to intrinsic functions
|
||
|
|
* in x86 microprocessors with SSE2 and later instruction sets up to AVX512.
|
||
|
|
*
|
||
|
|
* Instructions:
|
||
|
|
* Use Gnu, Clang, Intel or Microsoft C++ compiler. Compile for the desired
|
||
|
|
* instruction set, which must be at least SSE2. Specify the supported
|
||
|
|
* instruction set by a command line define, e.g. __SSE4_1__ if the
|
||
|
|
* compiler does not automatically do so.
|
||
|
|
*
|
||
|
|
* Each vector object is represented internally in the CPU as a vector
|
||
|
|
* register with 128, 256 or 512 bits.
|
||
|
|
*
|
||
|
|
* This header file includes the appropriate header files depending on the
|
||
|
|
* supported instruction set
|
||
|
|
*
|
||
|
|
* For detailed instructions, see VectorClass.pdf
