Abstract
A number of new interrupts, interrupt handlers, digital signal processing (DSP) tasks, registers and FIFOs are provided to an add-on fax/modem card and its host processor. The new FIFOs are used to facilitate rerouting of the transmit and receive data to the host for processing by the DSP task while maintaining compatibility, thereby off loading the add-on fax/modem card. The new interrupts and interrupt handling functions are used to facilitate the data rerouting, redirecting execution control between the host and the on-board processors with minimal latency. The new registers are used to facilitate the execution control redirection, transferring control and status information between the host and the on-board processors.
