MSC8101 Network Digital Signal Processor
The Freescale MSC8101 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
MSC8101 can execute up to four multiply-accumulate (MAC) operations in a single clock cycle. The MSC8101 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 MSC8101 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 MSC8101 offers 1500 DSP MMACS (1200 core and 300 EFCOP) performance using an internal 300 MHz
clock with a 1.6 V core and independent 3.3 V input/output (I/O).
