arm11 simd instruction

그나저나..ARM11의 SIMD 명령어 셋 목록 구하기 어렵네..

무슨 차이가 있나 보려고 했더니..

ARMv6 SIMD Features:

 75% performance increase for audio and video processing

 Simultaneous computation of 2x16-bit or 4x8-bit operands

 Fractional arithmetic

 User definable saturation modes (arbitrary word-width)

 Dual 16x16 multiply-add/subtract 32x32 fractional MAC

 Simultaneous 8/16-bit select operations

 Performance up to 3.2 GOPS at 800MHz

 Performance is achieved with a "near zero" increase in power consumption on a typical implementation
