This book provides design methods for Digital Signal Processors and Application Specific Instruction set Processors, based on the author's extensive, industrial design experience. Top-down and bottom-up design methodologies are presented, providing valuable guidance for both students and practicing design engineers. Coverage includes design of internal-external data types, application specific instruction sets, micro architectures, including designs for datapath and control path, as well as memory sub systems. Integration and verification of a DSP-ASIP processor are discussed and reinforced with extensive examples. - Instruction set design for application specific processors based on fast application profiling - Micro architecture design methodology - Micro architecture design details based on real examples - Extendable architecture design protocols - Design for efficient memory sub systems (minimizing on chip memory and cost) - Real example designs based on extensive, industrial experiences
