Comparing DSPs to “mathematical prodigies”: while ordinary CPUs (like MCUs) excel at multitasking (the “liberal arts students”), DSPs specialize in quickly solving complex equations (the “science students”), achieving “mental calculation abilities” through hardware acceleration (such as MAC units), making them suitable for the “high-intensity mathematics competitions” of real-time signal processing. 1. Core Functions and Architectural … Read more
