4 / 60 page ADSP-21161N –4– REV. A The ADSP-21161N continues SHARC’s industry-leading standards of integration for DSPs, combining a high performance 32-bit DSP core with integrated, on-chip system features. These features include a 1 M bit dual ported SRAM memory, host processor interface, I/O processor that supports 14 DMA channels, four serial ports, two link ports, SDRAM controller, SPI interface, external parallel bus, and glueless multiprocessing. The block diagram of the ADSP-21161N on Page 1 illustrates the following architectural features: • Two processing elements, each made up of an ALU, Mul- tiplier, Shifter, and Data Register File • Data Address Generators (DAG1, DAG2) • Program sequencer with instruction cache • PM and DM buses capable of supporting four 32-bit data transfers between memory and the core every core processor cycle • Interval timer • On-Chip SRAM (1 M bit) • SDRAM Controller for glueless interface to SDRAMs • External port that supports: • Interfacing to off-chip memory peripherals • Glueless multiprocessing support for six ADSP- 21161N SHARCs • Host port read/write of IOP registers • DMA controller • Four serial ports • Two link ports • SPI compatible interface • JTAG test access port • 12 General-Purpose I/O Pins Figure 1 shows a typical single-processor system. A multiprocess- ing system appears in Figure 4 on Page 8. Figure 1.
