DSP56156规格书详情
The DSP56156 is a general-purpose MPU-style Digital Signal Processor (DSP). On a single semiconductor chip, the DSP56156 comprises a very efficient 16-bit digital signal processing core, program and data memories, a number of peripherals, and system support circuitry. Unique features of the DSP56156 include a built-in sigma-delta (²ý) codec and phase-locked loop (PLL). This combination of features makes the DSP56156 a cost-effective, high-performance solution for many DSP applications, especially speech coding, digital communications, and cellular base stations.
