What are the different types of processors used in embedded system?

Answer 1

Wel,u have the Intel p 1 and p2 p3 p4 then centrino and then core duo and then centrino duo then centrino duo core duo also u have the amd athlon whis is standard

Now yow have Quad Core, I3, I5, I7 Processors

Answer 2

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 signal processor (DSP)

A DSP is optimized to efficiently perform repetitive and numerically intensive tasks such as matrix operations, convolution for filtering in real-time, because of the performance limitations of the MCUs. DSPs can run at very high clock rates, and they are often compared in terms of how many millions of MAC operations they can perform per second. This metric is known as "mega MACS," or MMACS.

A DSP is optimized to do mathematical operations, but not for supervisory control. Thus, DSP-based systems are integrated with the slower MCUs, this can be done in 2 ways:

Discrete DSP + MCU (separate in the system)

Advantages:

design of DSP and MCU separate from each other

Disadvantages:

hard partitioning between control and DSP function, if there are too many instructions for the DSP, the MCU can't take over

the DSP and MCU require different development tools

Convergent Processor [2](a convergent processor is optimized both for computation on real-time data flows, and for control-oriented tasks)

Advantages:

optimised for computation on real-time data flows as well as for control-oriented tasks

high clock rates

lower power dissipation

Disadvantages:

mixing a control application with signal processing on the same device, non-real-time tasks may interfere with time-critical tasks

the skills of developers must be higher
