The Spectrum Digital eZdsp™ and DSK modules are stand alone modules that allow users examine and evaluate certain characteristics of Texas Instruments digital signal processors (DSP) to determine if this DSP meets their application requirements. This eZdsp™ and DSK modules have on-board JTAG emulation scan controllers. The board is interfaced with the host computer via USB or parallel port. Therefore, the module may be operated without additional development tools such as a JTAG emulator. Furthermore, the module is an excellent platform to develop, demonstrate, and run software on TI's DSPs. The eZdsp™ and DSK modules allows full speed verification of DSP code. Expansion connectors are provided for any necessary evaluation circuitry or peripherals not provided on the shipped configuration.
