TABLE OF CONTENTS
GENERAL DESCRIPTION
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.
