TMS320C6000 DSP Expansion Bus: Multiple DSP Connection Using Asynchronous Host Mode Kyle Castille TMS320C6000 DSP Applications ABSTRACT You can easily interface multiple TMS320C6000E DSP devices to each other by way of a direct connection of the expansion bus (XBus). Each device’s XBus I/O port masters the other’s XBus host port configured for asynchronous slave mode. This application report highlights the XBus asynchronous host mode and XBus asynchronous I/O mode and explains the interface used to connect two C6000s together using these two interfaces. This application report contains: • Full example of a two-DSP interface via the asynchronous I/O mode and the asynchronous host mode at the XBus • Timing diagrams illustrating the interface functionalit =====================================================================
