The ADSP-2146x  fourth-generation SHARC Processors offer a high-performance core, plus application- and  audio-specific peripherals, making them ideal for professional and automotive  audio applications. Their single-instruction, multiple-data (SIMD) core supports  32-bit fixed-point and 32-/40-bit floating-point arithmetic formats—performing  at up to 2.7 GFLOPS and 900 MMACS with a 450-MHz clock. The DMA controllers  support 67 channels, each of which can transfer 32-bit serial data at peripheral  clock speed without slowing processor execution. The digital audio interface  (DAI) includes eight serial ports, four precision clock generators, an input  data port, an S/PDIF transceiver, and a flexible signal-routing unit (SRU). The  digital peripheral interface (DPI) includes two SPI ports, two timers, a UART, a  DTCP cipher, and a 2-wire interface. Two 8-bit, bidirectionally programmable  link ports can connect to the link ports of other DSPs or peripherals. 5 Mbits  of RAM and 4 Mbits of ROM are included on-chip. The following table compares the  various models.
