What is the purpose of a DSP processor?
A DSP processor is otherwise known as a digital signal processor, whose role is to convert analogue signals by reading them by measuring, filtering and compressing them. This stream of features are known as algorithms, when mathematical operations have to be quickly performed.
application specific instruction-set processor (ASIP) An ASIP is designed for a particular class of applications with common characteristics it's an 'intermediate' solution between a general-purpose and a single-purpose processor and gives more flexibility than a single purpose processor and still better performance, power, size than a general purpose processor. Of course this leads to a longer design time (cost) and there's also a compiler problem, you will have to create your compiler usually yourself. example:Digital…
DSP's are mainly based on Harvard architecture to perform task faster with hard wired instructions as compared to Microcontrollers which are mainly available with von neumann architecture (some microcontrollers like PIC is an exception). The DSP can compute the numerical parts of your application faster than the microcontroller can. Because that's what it's designed to do. You might also find that DSPs have more of the "right sort" of integrated peripherals, compared to microcontrollers.
good example for RISC processors is DSP (Digital signal processing) processors. simillarly for cisc processors is microprocessor.we can understand the difference between these two by a simple example. here it is, Convolution in terms of DSP is nothing but continuous multiplication. cisc processor performs multiplication by continious addition.but risc processor perform continious multiplication in a single pipeline architecture.
Strictly speaking, none: it uses one main DSP (digital signal processor) plus a backup DSP, but these are not microprocessors in the traditional sense. One could also ague that they are, depending on how inclusive you want to the term to be. There are other semi-intelligent chips on the PCB, which, once again, could be called microprocessors if one stretches the definition even farther.
Most modern cell phones contain two different computers and a microwave transmitter/receiver. The first computer uses a standard general purpose microprocessor for general data handling and call management purposes, the second computer uses a special purpose microprocessor called a digital signal processor (DSP) for handling voice processing and often photo compression/decompression processing. Of course there is also a battery, display, and touch sensor array.
The central processing unit of a computer is the central processor that controls everything else. In a general purpose computer it is a general purpose processor with arithmetic and logical capabilities. The 8086 was designed to be the central processing unit of a computer, but so were a lot of other chips.
