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.
