ADSP-2104 Microprocessor

16-Bit Fixed-Point DSP Microprocessors with On-Chip Memory

The ADSP-2104 and ADSP-2109 processors are single-chip

microcomputers optimized for digital signal processing (DSP)

and other high speed numeric processing applications. The

ADSP-2104/ADSP-2109 processors are 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 (ADSP-2109 contains 4K

words of program ROM), a programmable timer, and two

serial ports.

Fabricated in a high speed, submicron, double-layer metal

CMOS process, the ADSP-2104/ADSP-2109 operates at

20 MIPS with a 50 ns instruction cycle time. The ADSP-2104L

and ADSP-2109L are 3.3 volt versions which operate at

13.824 MIPS with a 72.3 ns instruction cycle time. Every

instruction can execute in a single cycle. Fabrication in CMOS

results in low power dissipation.
