5. Overview:
Digital signal processing techniques and algorithms
developed throughout history are useless, unless
implemented in a given hardware to perform specified tasks.
However, conventional microprocessors cannot handle
those algorithms.
Hence, there’s a need to develop a new hardware : the
Digital Signal Processor.

8. Introduction to DSProcessors:
From Wikipedia, the free encyclopedia:
A digital signal processor (DSP) is a specialized
microprocessor with an architecture optimized for the
operational needs of digital signal processing.
Typical DSP system :
9. Conversion from Analog to Digital and
Digital to Analog signals.
A lot of Interaction with outside world.
10. What are the Differences
between a DSP and a GP MPU
?

15. First DSP: 1978 : Texas Instruments TMS5100 DSP.
1978 : Intel and AMI, released to unsuccessful DSPs the
2920 and the S2811.
1980 : the NEC µPD7720 DSP by PSTN
Telecommunications.
16. 1983 : the TMS32010 by Texas instruments (Harvard architecture) (It already
had a special instruction set, with instructions like load-and-accumulate or
multiply-and-accumulate. It could work on 16-bit numbers and needed 390 ns
for a multiply–add operation. TI is now the market leader in general-purpose
DSP)
1988 : the appearance of the 2nd generation of DSPs, like AT&T DSP16A
and the Motorola 56000 (accelerating tight-loops and loop addressing).
1995: the appearance of the 3rd generation of DSPs : new special instructions
in the data path and hardware acceleration, using very complex problems like
Fourier-Transform, or Matrix Operations like “ Motorola MC 68356. And TI
TMS 320C541 and the TMS 320C80.
The fourth generation is best characterized by the changes in the instruction
set and the instruction encoding/decoding.
The fastest digital signal processor (DSP) is the TMS320C6416, by
Texas Instruments (USA). On 12 March 2003, a clock speed of 720
megahertz (MHz) was demonstrated at the Texas Instruments
Laboratories, Stafford, Texas, USA.
