What Is Signal Processing
A branch of mathematics
Is often considered part of electrical engineering
Has many applications in other fields
DSP Vs. Analog Electronics
DSP systems are programmable
Fixed performance
Are there any advantages to analog electronics?
DSPs Vs Microprocessors
Single-Cycle Multiply-accumulate capability
Specialized addressing modes
Memory
Specialized execution control
Irregular instruction sets
Applications of TMS320C31
Targeted at digital audio, data comm, and industrial automation
Consists of a multiplier,barrel shifter, ALU and a register file containing eight 40-bit fp registers
No support for rounding when converting fpinteger
Lower 8 bits are chopped off
Shifter can shift up to 32 bits left or right
All operations performed in a single clock cycle; some in parallel
