What is the difference between MPU, GPP, DSP

[leechat2001]

difference between gpp and dsp

I guess MPU is part of DSP
and GPP is general purpose processor

I am really confused about MPU part

gpp dsp

MicroProcessor Unit: another name for CPU, but the more popular term when referring to DSPs.

GPP is the General Purpose Preprocessor

DSP is in effect a microprocessor dedicated to "Digital Signal Processing" much of what is done in a GPP in software, is often implemented in hardware for much faster processing. Used in many fields, image recognition being one of them. MPU is just a general term and is a "Micro Processor Unit". Hope this helps.
