GENERAL DESCRIPTION
The ADSP-2100 Family processors are single-chip micro-
computers optimized for digital signal processing (DSP)
and other high speed numeric processing applications. The
ADSP-21xx processors are all built upon a common core. Each
processor combines the core DSP architecture—computation
units, data address generators, and program sequencer—with
differentiating features such as on-chip program and data
memory RAM, a programmable timer, one or two serial ports,
and, on the ADSP-2111, a host interface port.

Analog Devices ADSP2101
ADSP-21xx
Fabricated in a high speed, submicron, double-layer metal
CMOS process, the highest-performance ADSP-21xx proces-
sors operate at 25 MHz with a 40 ns instruction cycle time.
Every instruction can execute in a single cycle. Fabrication in
CMOS results in low power dissipation.
The ADSP-2100 Family’s flexible architecture and compre-
hensive instruction set support a high degree of parallelism.
In one cycle the ADSP-21xx can perform all of the following
operations:
Generate the next program address
Fetch the next instruction
Perform one or two data moves
Update one or two data address pointers
Perform a computation
Receive and transmit data via one or two serial ports
Receive and/or transmit data via the host interface port
(ADSP-2111 only)
The ADSP-2101, ADSP-2105, and ADSP-2115 comprise the
basic set of processors of the family. Each of these three devices
contains program and data memory RAM, an interval timer,
and one or two serial ports. The ADSP-2103 is a 3.3 volt
power supply version of the ADSP-2101; it is identical to the
ADSP-2101 in all other characteristics. Table I shows the
features of each ADSP-21xx processor.
The ADSP-2111 adds a 16-bit host interface port (HIP) to the
basic set of ADSP-21xx integrated features. The host port
provides a simple interface to host microprocessors or
microcontrollers such as the 8031, 68000, or ISA bus.
