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 Familyâs 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:

â¢ Generate the next program address

â¢ Fetch the next instruction

â¢ Perform one or two data moves

â¢ Update one or two data address pointers

â¢ Perform a computation

â¢ Receive and transmit data via one or two serial ports

â¢ 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.
