Figure 1. MSC7116 Block Diagram
The MSC7116 device is a highly integrated DSP processor that contains the StarCore™ SC1400 core, 384 KB of SRAM
memory, 16 KB 16-way instruction cache, 8 KB boot ROM, two 128-channel time-division multiplexing (TDM) interfaces
with hardware support for µ/A-law decoding/encoding, a UART, a 32-channel DMA controller, a 16-bit host interface
(HDI16) to support an external host processor, a 10/100Base-T MII/RMII, a programmable interrupt controller (PIC), an I2C
interface, two 16-bit quad cascadable timers, GPIO signals, and an on-chip emulator (OCE) and an event port for enhanced
debug and system integration capability. The SC1400 core has four ALUs and performs at 1000 DSP million multiply-
accumulates per second (MMACS) with an internal 266 MHz clock at 1.2 V.
