Preliminary Technical Data
SUMMARY
High performance 32-bit/40-bit floating point processor
optimized for professional audio processing
At 333 MHz/2 GFLOPs, with unique audio centric peripherals
such as the Digital Audio Interface the ADSP-21363 SHARC
processor is ideal for applications that require industry
leading equalization, reverberation and other effects
processing
Single-Instruction Multiple-Data (SIMD) computational
architecture
Two 32-bit IEEE floating-point/32-bit fixed-point/40-bit
extended precision floating-point computational units,
each with a multiplier, ALU, shifter, and register file
