3 unusual facts about Very long instruction word


Transmeta Efficeon

The Efficeon processor is Transmeta's second-generation 256-bit VLIW design which employs a software engine to convert code written for x86 processors to the native instruction set of the chip (Code Morphing Software, aka CMS).

Very long instruction word

Examples of contemporary VLIW CPUs include the TriMedia media processors by NXP (formerly Philips Semiconductors), the SHARC DSP by Analog Devices, the C6000 DSP family by Texas Instruments, and the STMicroelectronics ST200 family based on the Lx architecture (also designed by Josh Fisher).

An architecture designed for use in signal processing may have a number of special-purpose instructions to facilitate certain complicated operations such as fast Fourier transform (FFT) computation or certain calculations that recur in tomographic contexts.
