The Freescale MSC8103 DSP is a very versatile device that integrates the high-performance SC140 four-ALU (arithmetic logic unit) DSP core along with 512 KB of internal memory, a communications processor module (CPM), a 64-bit bus, a very flexible system integration unit (SIU), and a 16-channel DMA engine on a single device. With its four-ALU core, the MSC8103 can execute up to four multiply-accumulate (MAC) operations in a single clock cycle. The MSC8103 CPM is a 32-bit RISC-based communications protocol engine that can network to time-division multiplexed (TDM) highways, Ethernet, and asynchronous transfer mode (ATM) backbones. The MSC8103 60x-compatible bus interface facilitates its connection to multi-master system architectures. The very large internal memory, 512 KB, reduces the need for external program and data memories. The MSC8103 offers 1200 DSP MMACS performance using an internal 300 MHz clock with a 1.6 V core and independent 3.3 V input/output (I/O).
