GENERAL NOTE
This data sheet provides preliminary information for the
ADSP-21992 Mixed Signal Digital Signal Processor.
GENERAL DESCRIPTION
The ADSP-21992 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 Process-
ing applications that require the combination of a high
performance DSP and the mixed signal integration of
embedded control peripherals such as analog to digital con-
version with communications interfaces such as CAN.
The ADSP-21992 integrates the 160 MIPS, fixed point
ADSP-219x family base architecture with a serial port, an
SPI compatible port, a DMA controller, three programma-
ble 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 pro-
cessing in a highly integrated environment.
The ADSP-21992 architecture is code compatible with
previous ADSP-217x based ADMCxxx products. Although
the architectures are compatible, the ADSP-21992, with
ADSP-219x architecture, has a number of enhancements
over earlier architectures. The enhancements to computa-
tional units, data address generators, and program
sequencer make the ADSP-21992 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, two’s complement value and base address
registers for easier implementation of circular buffering.
The ADSP-21992 integrates 48K words of on chip memory
configured as 32K words (24-bit) of program RAM, and
16K words (16-bit) of data RAM.
Fabricated in a high speed, low power, CMOS process, the
ADSP-21992 operates with a 6.25 ns instruction cycle time
(160 MIPS). All instructions, except two multiword
instructions, execute in a single DSP cycle.
The ADSP-21992’s flexible architecture and comprehen-
sive instruction set support multiple operations in parallel.
For example, in one processor cycle, the ADSP-21992 can:
Generate an address for the next instruction fetch
Fetch the next instruction
Perform one or two data moves
Update one or two data address pointers
Perform a computational operation
These operations take place while the processor
continues to:
Receive and transmit data through the serial port
Receive or transmit data over the SPI port
Access external memory through the external memory
interface
Decrement the timers
Operate the embedded control peripherals (ADC, PWM,
EIU, etc.)
DSP Core Architecture
6.25 ns instruction cycle time (internal), for up to 160
MIPS sustained performance
ADSP-218x family code compatible with the same easy
to use algebraic syntax
Single cycle instruction execution
Up to 1 Mwords of addressable memory space with
twenty four bits of addressing width
Dual purpose program memory for both instruction and
data storage
Fully transparent Instruction Cache allows dual operand
fetches in every instruction cycle
Unified memory space permits flexible address genera-
tion, using two independent DAG units
Independent ALU, Multiplier/Accumulator, and barrel
Shifter computational units with dual 40-bit
accumulators
Single cycle context switch between two sets of computa-
tional and DAG registers
Parallel execution of computation and memory
instructions
Pipelined architecture supports efficient code execution
at speeds up to 160 MIPS
Register file computations with all non-conditional,
non-parallel computational instructions
Powerful Program Sequencer provides zero overhead
looping and conditional instruction execution
