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 onboard 64K of external SRAM and Cr
ystal 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.
