Signal Processor (DSP is the core of the Digital
revolution, no matter in the application of
breadth or depth is still at an unprecedented
rate of forward development. Digital signal
processing is to use computer or special
treatment equipment, in digital form on signal
is analyzed, collection, synthesis, transform,
filtering and estimation, compression,
identification processing, in order to extract
useful information and effective transmission
and applications.
This paper provides UART for a solution to
communication between DSP and PC. The serial
communication between DSP and personal computer can be realized by using UART
CMOS chip of Texas Instruments Inc., which can avoid writing the complicated
software routine for the McBSP of DSP, and has the advantages of simple
programming high transmission capability, good reliability and real time capability.
In this paper, we introduce briefly a kind of UART COMS chip TL16C550
and provide the hardware circuit between
