What is difference between DSP and CPU?
The main difference between a DSP and a microprocessor is that a DSP processor has features designed to support high-performance, repetitive, numerically intensive tasks. DSPs also tend to be two to three times as fast as general-purpose microprocessors. This is because of architectural differences.
How many functional units are there in CPU of tms320c67x DSP?
Two data paths, each with four functional units. 32 32-bit registers. Control registers. Control logic Test, emulation, and interrupt logic.
Which processor is used in DSP?
A digital signal processor (DSP) is a specialized microprocessor chip, with its architecture optimized for the operational needs of digital signal processing. DSPs are fabricated on MOS integrated circuit chips.

What are the features of DSP processor?
They provide high-speed data processing by implementing single instruction, multiple data (SIMD) operations, special instructions for superscalar architectures cores, single-cycle MAC or fused multiply–add (FMA) computation, parallel computation in several MAC units, fast data streaming using DMA, circular buffering …
What are the eight functional units of CPU in tms320c67x DSP?
The CPU contains:
- Program fetch unit.
- Instruction dispatch unit.
- Instruction decode unit.
- Two data paths, each with four functions units.
- 32 32-bit registers.
- Control logic.
- Test, emulation and interrupt logic.
What is the reason for need of high speed DSP?
6. What is the reason for the need of high speed DSP? Explanation: The time taken for input/output and the processing time together must be smaller than the sampling period to ensure the continuous flow of data.
What is a DSP board?
DSP boards or digital signal processor computer boards are central to the implementation of high-performance industrial systems. They collect and process digital data from many sources, and distribute the results to other elements of the system. PCI is a local bus system designed for high-end computer systems.
