Advance Information
DSP56362
24-Bit Audio DIgital Signal Processor
Motorola designed the DSP56362 to support digital audio applications requiring digital audio
compression and decompression, sound field processing, acoustic equalization, and other digital
audio algorithms. The DSP56362 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 DSP56362
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”
“deasserted”
Examples:
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
Means that a high true (active high) signal is low or that a low true (active low)
signal is high
