Reference material by Wikibooks contributors. This retains its source identity and is not 411 news reporting.
The instruction set of the original x86 processor, the 8086, has been expanded upon and improved many times since its introduction. Among the new features added by these extensions are new registers, more instructions. They have also facilitated the move from 16- to 32-bit (and now from 32- to 64-bit). These chapters will cover the following extensions:
MMX, by Intel in 1996
SSE, by Intel in 1999
3D Now!, by AMD in 1998
