MSC8122TMP6400V

Digital Signal Processor Dsp Overview

The MSC8122 is a quad-core digital signal processor featuring four StarCore SC140 DSP extended cores. Each core integrates an SC140 DSP, 224 Kbyte of internal SRAM (M1), and a 16-way 16 Kbyte instruction cache. The device includes 475 Kbyte of M2 memory for critical data buffering and a 4 Kbyte boot ROM. It utilizes an M2-accessible multi-core MQBus operating at the core frequency with up to 128-bit reads. A 60x-compatible system bus supports 32 or 64-bit data widths, while a Direct Slave Interface (DSI) provides external host access. The processor incorporates a flexible memory controller, a multi-channel DMA controller, TDM modules, an Ethernet controller, and GPIO ports.
