	Streaming SIMD Extensions - Wikipedia, the free encyclopedia
		SSE (Streaming SIMD Extensions) is a SIMD (Single Instruction, Multiple Data) instruction set designed by Intel, and introduced in their Pentium III series processors as a reply to AMD's 3DNow!
		Integer SIMD operations may still be performed with the eight 64-bit MMX registers.
		On the Pentium 3, however, SSE is implemented using the same circuitry as the FPU, meaning that, once again, the CPU cannot issue both FPU and SSE instructions at the same time for pipelining.

		Because Itanium instructions treat the Streaming SIMD Extensions registers in the same way whether you are using packed or scalar data, there is no __m32 data type to represent scalar data.
		Streaming SIMD Extensions intrinsics are defined for the __m128 data type, a 128-bit quantity consisting of four single-precision FP values.
		Many of the Streaming SIMD Extensions intrinsics for Itanium-based systems were created for compatibility with existing IA-32 intrinsics and not for performance.

		MMX and SSE, both of which are instruction sets that have been added to existing architectures, share the concept of SIMD, but they differ in the data types they handle, and in the way they are supported in the processor.
		Of the 70, 50 are SIMD for floating point, 12 are for SIMD integer, and the remaining eight are cacheability instructions.
		The primary benefit of SSE is a reduction in the number of instructions executed for the given data set.

		The Streaming SIMD Extensions is a natural extension of SIMD-style processing which was initiated when MMX technology was launched.
		The Streaming SIMD Extensions include three basic categories of instructions: SIMD floating-point instructions, SIMD integer instructions, and memory-related cache-control instructions.
		Well, keep in mind that data should be 16-byte aligned to avoid performance penalties, and that the Pentium III requires 16-byte alignment when reading and writing the Streaming SIMD Extensions registers (since their new registers are 128 bits wide).

		SSE is similar to MMX; in fact, besides being called KNI (Katmai New Instructions), SSE was also called MMX-2 by some before it was released.
		SSE also supports data prefetching, which is a mechanism for reading data into the cache before it is actually called for.
		Note that for any of the SSE instructions to be beneficial, they must be encoded in the software you are using, which means that SSE-aware applications must be used to see the benefits.
