Overview
Overview .....................................i
Features .................................... ii
The DSP56364 supports digital audio applications requiring sound field processing,
acoustic equalization, and other digital audio algorithms. The DSP56364 uses the
high performance, single-clock-per-cycle DSP56300 core family of programmable
CMOS digital signal processors (DSPs) combined with the audio signal processing
capability of the Motorola Symphony™ DSP family, as shown in Figure 1. This
design provides a two-fold performance increase over Motorola’s popular
Symphony family of DSPs while retaining code compatibility. Significant
architectural enhancements include a barrel shifter, 24-bit addressing, instruction
cache, and direct memory access (DMA). The DSP56364 offers 100 million
instructions per second (MIPS) using an internal 100 MHz clock at 3.3 V.

Data Sheet Conventions
This data sheet uses the following conventions:
OVERBAR
“asserted”
Used to indicate a signal that is active when pulled low (For
example, the RESET pin is active when low.)
Means that a high true (active high) signal is high or that a low
true (active low) signal is low
“deasserted” Means that a high true (active high) signal is low or that a low
true (active low) signal is high
