Dsp Microcomputer - Analog Devices

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 manipulationsbit 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-2181s flexible architecture and comprehensive instruction set allow the processor to perform multiple opera- tions in parallel. By Analog Devices, Inc.
