GENERAL DESCRIPTION
The ADSP-2181 is a single-chip microcomputer optimized for
digital signal processing (DSP) and other high speed numeric
processing applications.
The ADSP-2181 combines the ADSP-2100 family base archi-
tecture (three computational units, data address generators and
a program sequencer) with two serial ports, a 16-bit internal
DMA port, a byte DMA port, a programmable timer, Flag I/O,
extensive interrupt capabilities, and on-chip program and data
memory.
The ADSP-2181 integrates 80K bytes of on-chip memory con-
figured as 16K words (24-bit) of program RAM, and 16K words
(16-bit) of data RAM. Power-down circuitry is also provided to
meet the low power needs of battery operated portable equip-
ment. The ADSP-2181 is available in 128-lead TQFP and 128-
lead PQFP packages.
In addition, the ADSP-2181 supports new instructions, which
include bit manipulations—bit set, bit clear, bit toggle, bit test—
new ALU constants, new multiplication instruction (x squared),
biased rounding, result free ALU operations, I/O memory trans-
fers and global interrupt masking for increased flexibility.
Fabricated in a high speed, double metal, low power, CMOS
process, the ADSP-2181 operates with a 25 ns instruction cycle
time. Every instruction can execute in a single processor cycle.
The ADSP-2181’s flexible architecture and comprehensive
instruction set allow the processor to perform multiple opera-
tions in parallel. In one processor cycle the ADSP-2181 can:
Generate the next program address
Fetch the next instruction
Perform one or two data moves
Update one or two data address pointers
Perform a computational operation
