The DSP56374 supports digital audio applications  
requiring sound field processing, acoustic equalization,  
and other digital audio algorithms. The DSP56374 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 Freescale Semiconductor,  
Inc. Symphony™ DSP family, as shown in Figure 1.  
Significant architectural enhancements include a barrel  
shifter, 24-bit addressing, and direct memory access
