主　　题：SIGNAL PROCESSING 

摘      要：An approach to solving the speed requirements associated with modern control algorithms is to use a special kind of processor chip. Digital signal processors (DSPs) are constructed to speedily perform the kinds of arithmetic operations associated with digital filtering and processing. Most DSPs are built with what is called a Harvard architecture. This configuration is unlike conventional computer architectures in that it employs separate data and instruction memories that are accessed by separate buses. The benefit of this arrangement is increased speed because instructions and data can move in parallel instead of sequentially. In addition, these integrated circuits (ICs) generally carry high-speed hardware multipliers and fast on-chip memories that eliminate delays associated with shuttling information on and off chip to peripheral devices. This promotes fast program execution.
