SHARC^®Processor

ADSP-21375

Preliminary Technical Data

SUMMARY

High performance 32-bit/40-bit floating point processor

optimized for high performance audio processing

Single-instruction, multiple-data (SIMD) computational

architecture

On-chip memory—0.5M bit of on-chip SRAM and a dedicated

2M bit of on-chip mask-programmable ROM

Code compatible with all other members of the SHARC family

The ADSP-21375 is available with a 266 MHz core instruction

rate with unique audio centric peripherals such as the digi-

tal applications interface, serial ports, precision clock

generators and more. For complete ordering information,
