The ADSP-21xx series Fixed-point digital signal processors from Analog Devices are code- and pin-compatible DSPs with performance up to 160 MHz and power as low as 184 microamps. The ADSP-21xx family is ideal for speech processing and voice-band modems, as well as real-time control applications.
Features
The main features of ADSP-21xx series Fixed-point digital signal processors may be summarized as follows:
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 an on-chip program and data memory RAM, a programmable timer, one or two serial ports, and, on the ADSP-2111, a host interface port. The ADSP-2111 adds a 16-bit host interface port (HIP) to the basic set of ADSP-21xx integrated features.
