SHARC Processor
ADSP-21483/ADSP-21486/ADSP-21487/ADSP-21488/ADSP-21489
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—5 Mbits on-chip RAM, 4 Mbits on-chip
ROM
Up to 450 MHz operating frequency
Code compatible with all other members of the SHARC family
The ADSP-2148x processors are available with unique audio-
centric peripherals, such as the digital applications
interface, serial ports, precision clock generators, S/PDIF
transceiver, asynchronous sample rate converters, input
data port, and more
