Digital Signal Processing 101--dsp System Design Course (1)

Part 1: Why DSP? Advantages of DSP architecture and DSP over traditional Analog Circuits

Comparison between DSP and MCU: 1. Faster processing speed 2. Built-in high-speed hardware multiplier? Enhanced multi-level pipeline (high-speed data computing capability) 3. Improved larger storage structure the haver structure has independent programs and data spaces. What is DSP? It is a microprocessor that integrates hardware, software, and various commands to achieve faster computation. It is often used in signal processing. After the original signal is input, the DSP processes (filtering, conversion, or other operations) and then outputs the data for other operations. The typical DSP system should include the mathematical computing unit, memory management unit, parallelism, bus, instruction set, etc. The difference between DSP and analog circuit is that DSP can be easily changed. However, the price is relatively higher. Two types of filter design are generally available: FIR finite pulse filter: the structure of FIR infinite pulse filter is shown in: The main difference is that infinite pulse filter is a feedback link.
