DSP56362 Datasheet 24-bit Audio Digital Signal Processor

Manufacturer: Freescale Semiconductor (now NXP Semiconductors)

Overview: Freescale Semiconductor Technical Data Document Number: DSP56362 Rev. 4, 08/2006 DSP56362 24-Bit Audio Digital Signal Processor 1 Overview Freescale Semiconductor, Inc. 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 Freescale Symphony™ DSP family, as shown in Figure 1-1. This design provides a two-fold performance increase over Freescale’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. Contents 1 Overview . . . . . . . . . . . . . . . . . . . . . . . . . . . .
