嵌入式硬件设计参考系列之如何选择 DSP 处理器？.pdf Choosing a DSP Processor Berkeley Design Technology, Inc. Introduction A second feature shared by DSP processors is the ability to complete several accesses to memory in a sin- DSP processors are microprocessors designed to per- gle instruction cycle. This allows the processor to fetch form digital signal processing―the mathematical ma- an instruction while simultaneously fetching operands nipulation of digitally represented signals. Digital signal and/or storing the result of a previous instruction to processing is one of the core technologies in rapidly memory. For example,……
