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 that includes a high-
precision 8-channel asynchronous sample rate converter
among others, the ADSP-21364 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
SHARC® Processor
ADSP-21364
On-chip memory—3M bit of on-chip SRAM and a dedicated
4M bit of on-chip mask-programmable ROM
Code compatible with all other members of the SHARC family
The ADSP-21364 is available with a 333 MHz core instruction
rate and unique audio centric peripherals such as the Digi-
tal Audio Interface, S/PDIF transceiver, serial ports, 8-
channel asynchronous sample rate converter, precision
clock generators and more. For complete ordering infor-
mation, see Ordering Guide on Page 52
