7. DSP Interface Depending upon the DSP that the user chooses there are a number of TI DSKs available DSKs are DSP Starter Kits and provide users with a DSP starter system They contain all the necessary hardware and software to quickly begin prototype construction For example the TMS320C6711 DSP starter kit includes the DSK hardware a parallel port cable to connect to a PC a 5 V universal power supply and a Code Composer Studio CD ROM containing all the necessary software Each family of DSKs provides different physical interface options These interface options enable address data and control signals to be decoded and used by mezzanine level cards such as EVMs To connect this EVM to any DSK requires selection of the correct interface card Generally the procedure is outlined below Y Select the DSP you wish to use Select the appropriate DSK Y Select the suitable interface card As an example assume that the user wishes to use the TLC3578 EVM with the TMS320C6711 DSP the steps that should be taken are shown below following a side elevation of the boards required 5 2 Additional Hardware Options Figure 5 1 EVM Selection TMS320C2000 Interface Card TLC3574 EVM TMS320C6711 TMS320C6711 TMS320C3000 DSP DSK Interface Card TLC3578 EVM TLC3544 EVM TMS320C5K 6K Interface Card TLC3548 EVM 1 Select DSP 2 Select DSK 3 Select Interface Card TLC3578 EVM TLC3574 EVM Figu
