SUMMARY
Note: This datasheet is preliminary. This document contains
material that is subject to change without notice.
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 of on-chip RAM, 4 Mbits of on-chip
ROM
Up to 300 MHz operating frequency
Code compatible with all other members of the SHARC family
The ADSP-2147x 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.
