TMS320C25 DSP Architecture and Features
[attachment=56093]
What is DSP ?
Digital Signal Processing (DSP) is used in a wide variety of applications, and it is hard to find a good definition that is general.
DSP Algorithm
Most share common features:
They use a lot of maths (multiplying and adding signals)
They deal with signals that come from the real world
They require a response in a certain time
History of the TMS320 family
TMS320C25, a CMOS 40-MHz digital signal processor capable of twice the performance of the TMS320C1x devices
is capable of executing 10 million instructions per second.
24 additional instructions (133 total)
eight auxiliary registers
Memory Organization
288 words are always data memory and the remaining 256 words may
be configured as either program or data memory.
The TMS320C2x can address a total of 64K words of data memory.
Direct Memory Access
In a multiprocessor environment, the SYNC input can be used to greatly ease interface between processors.
For multiprocessing applications, the TMS320C2xs allocates global data memory space and communicates with that space via the BR (bus request) and READY control signals.
