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—2M bits of on-chip SRAM and 6M bits of
on-chip mask programmable ROM
Code compatible with all other members of the SHARC family
The ADSP-21367/ADSP-21368/ADSP-21369 are available
with a 400 MHz core instruction rate with unique audiocen-
tric peripherals such as the digital applications interface,
S/PDIF transceiver, serial ports, 8-channel asynchronous
sample rate converter, precision clock generators, and
more. For complete ordering information, see
