SSE3, Streaming SIMD Extensions 3, also known by its Intel code name Prescott New Instructions (PNI), [1] is the third iteration of the SSE instruction set for the IA-32 (x86) architecture. Intel introduced SSE3 in early 2004 with the Prescott revision of their Pentium 4 CPU. [ 1 ]
SSSE3 was first introduced with Intel processors based on the Core microarchitecture on June 26, 2006 with the "Woodcrest" Xeons.. SSSE3 has been referred to by the codenames Tejas New Instructions (TNI) or Merom New Instructions (MNI) for the first processor designs intended to support it.
AMD added a subset of SSE, 19 of them, called new MMX instructions, [3] and known as several variants and combinations of SSE and MMX, shortly after with the release of the original Athlon in August 1999, see 3DNow! extensions. AMD eventually added full support for SSE instructions, starting with its Athlon XP and Duron (Morgan core) processors.
SSE2 extends MMX instructions to operate on XMM registers. Therefore, it is possible to convert all existing MMX code to an SSE2 equivalent. Since an SSE2 register is twice as long as an MMX register, loop counters and memory access may need to be changed to accommodate this.
A patch is data that is intended to be used to modify an existing software resource such as a program or a file, often to fix bugs and security vulnerabilities. [1] [2] A patch may be created to improve functionality, usability, or performance. A patch is typically provided by a vendor for updating the software that they provide.
SSE4 (Streaming SIMD Extensions 4) is a SIMD CPU instruction set used in the Intel Core microarchitecture and AMD K10 (K8L).It was announced on September 27, 2006, at the Fall 2006 Intel Developer Forum, with vague details in a white paper; [1] more precise details of 47 instructions became available at the Spring 2007 Intel Developer Forum in Beijing, in the presentation.

The CVT16 instruction set, announced by AMD on May 1, 2009, [2] is an extension to the 128-bit SSE core instructions in the x86 and AMD64 instruction set.. CVT16 is a revision of part of the SSE5 instruction set proposal announced on August 30, 2007, which is supplemented by the XOP and FMA4 instruction sets.
The CPU core is a two-way superscalar in-order RISC processor. [3] Based on the MIPS R5900, it implements the MIPS-III instruction set architecture (ISA) and much of MIPS-IV, in addition to a custom instruction set developed by Sony which operated on 128-bit wide groups of either 32-bit, 16-bit, or 8-bit integers in single instruction, multiple data (SIMD) fashion (e.g. four 32-bit integers ...
