3GPP, a global initiative that provides complete system specifications for cellular telecommunications network technologies, has adopted and released the new codec, which enables more efficient processing and improves battery life by leveraging modern DSP architectures with 64-bit accumulators, single instruction, multiple data (SIMD) and very long instruction word
According to Xbit Labs, one of the most important changes in architecture is that the new stream core (SC) design will feature VLIW-4 (very long instruction word
) architecture, unlike previous gen stream cores with VLIW-5 architecture.
The Very Long Instruction Word
-- Single Instruction Multiple Data (VLIW-SIMD) DSP architecture delivers breakthrough performance and low power consumption.
It is equipped with 1 MByte internal RAM and has a Very Long Instruction Word
Key changes include a complete rewrite of the code morphing software which feeds instructions to the architecture's Very Long Instruction Word
A Crusoe processor uses a Very-Long Instruction Word
(VLIW) instruction set at its core; CM software is responsible for the translation of x86 instructions to VLIW so that they can be processed by the CPU.
The MAP1000 architecture is designed to replace hard-wired multimedia engines as well as conventional microprocessors by integrating high-performance imaging into an advanced very-long instruction word
(VLIW) Central-Processing Unit (CPU).
A question that immediately comes to mind is: what fundamentally new techniques of the same importance as pipe-lining, superscalar, and very long instruction word
(VLIW) are being proposed today for use in processors 10 years from now?
The first programmable very long instruction word
processor (VLIW), the TM-1 will have sound, music, video, and graphics capabilities.
Further on down the line look for Intel and Hewlett-Packard to release a Very Long (or Large) Instruction Word
(VLIW) 64-bit CPU in 1997 or 1998.
MegaChips took advantage of the ultra-low power Xtensa processor architecture, which can perform both control and digital signal processing (DSP), customizing it for maximum throughput with three-way very long instruction word
(VLIW) processing, floating point, and four-way single instruction, multiple data (SIMD) processing.
