Abstract :
The author first discusses digital signal processing (DSP) characteristics. After reviewing historical digital signal processing solutions, he focuses on single-chip programmable digital signal processors and compares their architectural designs to those of general-purpose microprocessors and microcontrollers. Deficiencies of early digital signal processors are discussed and trends of DSP are explored. Performance and cost benefits of using DSP in digital control systems are explained. Automotive applications of digital signal processors are discussed in the areas of powertrain, body and chassis control, and entertainment systems. Finally, the challenges facing the automotive industry and semiconductor vendors are discussed
