Architecture of DSP processors have become a major topic ever since the development of digital signal processing. Digital signal processing is finding wider application in almost all the fields .So does the efforts to develop a faster digital signal processor, fast DSP processor requires more sophisticated architecture. Two main companies in this field are Texas Instruments and Analog Devices. Basic architecture of DSP processors by these companies are discussed here.
. . . . The major components can is illustrated below:
. . . 1. Fast and flexible arithmetic units 2. Extended dynamic registers 3. Single cycle fetch of two operands 4. Hard ware circular buffers 5. Zero over head looping and branching
. . . The DSP processors discussed below has modified Harvard architecture, features minimized power consumption and a high degree of parallelism.
