Low-Cost 16-Bit DSP with DDR Controller

The MSC7110 device is a highly integrated DSP processor that contains the StarCore™ SC1400 core, 64 KB of SRAM memory, a 16 KB ICache, an 8 KB boot ROM, a 128-channel time-division multiplexing (TDM) interface 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 programmable interrupt controller (PIC), an I2C interface, two 16-bit quad cascadable timers, GPIO signals, and an on-chip emulator (OCE) and event port for enhanced debug 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.
