ADI ADSP-2115BP-40

The ADSP-2115 is a single chip microcomputer optimized for digital signal processing (DSP) and other high speed numeric processing applications. Its instruction set is fully compatible with all other ADSP-2100 family processors. It combines the complete ADSP-2100 base architecture (three computational units, data address generators and a program sequencer) with two serial ports, a programmable timer, extensive interrupt capabilities and on-chip program and data memory. The ADSP-2115 has 512 words of (16-bit) data memory RAM and 1K words of (24-bit) program memory RAM on chip. Fabricated in a high speed, double layer metal CMOS process, the ADSP-2115 operates with a 60 ns instruction cycle time. Every instruction can execute in a single cycle. The flexible architecture and comprehensive instruction set of the ADSP-2115 supports a high degree of operational parallelism. In one cycle the ADSP-2115 can:

• generate the next program address
• fetch the next instruction
• perform one or two data moves
• update one or two data address pointers
• perform a computational operation receive and transmit data via the two serial ports
