DSP56307EVM Evaluation Module

The DSP56307 Evaluation Module (DSP56307EVM) is a low-cost platform for developing real-time

software and hardware products to support a new generation of wireless, telecommunications, and

multimedia applications. The DSP56307EVM targets applications requiring a large amount of on-chip

memory such as wireless infrastructure applications. The Enhanced Filter Coprocessor (EFCOP) can

accelerate general filtering algorithms, such as finite impulse response (FIR) filters, infinite impulse

response (IIR) filters; the EFCOP can also adapt FIR filters as multi-channel filters used in echo

cancellation , correlation, and general-purpose convolution-based algorithms. The user can download

software to on-chip or on-board RAM, then run and debug it. The user can also connect hardware, such as

external memories and analog-to-digital (A/D) or digital-to-analog (D/A) converters, for product

development. The 24-bit precision of the DSP56307 Digital Signal Processor (DSP) combined with the on-

board 64K of external SRAM and Crystal Semiconductor’s CS4218 stereo, CD-quality, audio codec

ideally suits the DSP56307EVM for implementing and demonstrating many communications and audio

processing algorithms. It is also an effective tool for learning the architecture and instruction set of the

DSP56307 processor. Figure 1 shows the functional block diagram for the DSP56307EVM.
