A digital signal processor (DSP) is a specialized microprocessor chip, with its architecture optimized for the operational needs of digital signal processing. [ 1 ] : 104–107 [ 2 ] DSPs are fabricated on metal–oxide–semiconductor (MOS) integrated circuit chips.
The category of digital signal processors includes all types and makes of signal processing microprocessors. Subcategories This category has only the following subcategory.
Qualcomm announced Hexagon Vector Extensions (HVX). HVX is designed to allow significant compute workloads for advanced imaging and computer vision to be processed on the DSP instead of the CPU. [19] In March 2015 Qualcomm announced their Snapdragon Neural Processing Engine SDK which allow AI acceleration using the CPU, GPU and Hexagon DSP. [20]
Digital signal processing (DSP) is the use of digital processing, such as by computers or more specialized digital signal processors, to perform a wide variety of signal processing operations. The digital signals processed in this manner are a sequence of numbers that represent samples of a continuous variable in a domain such as time, space ...
The 821 provides a 10% improvement in performance over the 820 due to a faster clocked CPU, but otherwise has similar features, with Qualcomm stating that the 821 is designed to complement rather than replace the 820. [178] Notable features over its predecessor (820): CPU features Faster CPU (+10%) GPU features Faster GPU 650 MHz from 624 (+5%)

The TMS320 architecture has been around for a while so a number of product variants have developed. The product codes used by Texas Instruments after the first TMS32010 processor have involved a series of processor named "TMS320Cabcd", where a is the main series, b the generation and cd is some custom number for a minor sub-variant.
This is a list of central processing units based on the ARM family of instruction sets designed by ARM Ltd. and third parties, sorted by version of the ARM instruction set, release and name. In 2005, ARM provided a summary of the numerous vendors who implement ARM cores in their design. [ 1 ]
