The ADSP-2100 Family processors are single-chip microcomputers 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. * 25 MIPS, 40 ns Maximum Instruction Rate * Separate On-Chip Buses for Program and Data Memory * Program Memory Stores Both Instructions and Data (Three-Bus Performance) * Dual Data Address Generators with Modulo and Bit-Reverse Addressing * Efficient Program Sequencing with Zero-Overhead Looping: Single-Cycle Loop Setup * Automatic Booting of On-Chip Program Memory from Byte-Wide External Memory (e.g., EPROM )
