Mixed Signal Dsp Co - Analog Devices

The ADSP-21991 is a mixed signal DSP controller based on the ADSP-219x DSP Core, suitable for a variety of high performance industrial Motor Control and signal processing applications that require the combination of a high performance DSP and the mixed signal integration of embedded control peripherals such as Analog-to-digital conversion. The ADSP-21991 integrates the fixed point ADSP-219x family base architecture with a serial port, an SPI compatible port, a DMA controller, three programmable Timers general-purpose Programmable Flag pins, extensive interrupt capabilities, on- chip program and data memory spaces, and a complete set of embedded control peripherals that permits fast Motor Control and signal processing in a highly integrated environment. The ADSP-21991 architecture is code compatible with previous ADSP-217x based ADMCxxx products. Although the architec- tures are compatible, the ADSP-21991 with ADSP-219x architecture, has a number of enhancements over earlier archi- tectures. The enhancements to computational units, data address generators, and program Sequencer make the ADSP-21991 more flexible and easier to program than the previous ADSP-21xx embedded DSPs Indirect addressing options provide addressing flexibility premodify with no update, pre- and post-modify by an immediate 8-bit, twos complement value and base address Registers for easier implementation of circular buffering. The ADSP-21991 integrates 40K words of on-chip memory con- figured as 32K words (24-bit) of program RAM, and 8K words (16-bit) of data RAM. Fabricated in a high speed, low power, CMOS process, the ADSP-21991 operates with a 6.25 ns instruction cycle time for a 160 MHz CCLK and with a 6.67 ns instruction cycle time for a 150 MHz CCLK. All instructions, except two multiword instructions, execute in a single DSP cycle. By Analog Devices, Inc.
