DSP/ uC/ uP
uP :
Very flexible for new alone system
design . It is a core sub- system so you
have to need memory, peripheral ...
for completion system. uC takes some
cycle clock system to complete one
instruction and data unit of them are
byte , word or more .
uC contens one uC and intergrated
peripheral . It is realbility so it often is
used in industry and applications
which request safety. Data unit of
them is bit and bit instruction
processing of them is flexible and very
fast . The speed of uC is not as fast as
uP
DSP is special uP used for signal
processing . Because, in DSP, there are
many paralle multipy hardware and
adder hareware so they take one cycle
clock system for a instruction .
Ussually , DSP can paralle process 8
instructions per cycle with low -cost,
high -performance . ... Now, DSP
ussually use in wireless device, PDA or
signal processing card.
