Abstract: In a system having an DSP, an ASIC and a memory, in which the ASIC generates a number of different competing interrupts for the DSP to service, the ASIC has an interrupt request control module which automatically provides the DSP with a vector pointing to the memory location of the interrupt service routine for the currently pending interrupt request having the highest priority of all pending requests. The DSP reads this vector and uses it to access the interrupt service routine in the memory. Reading of this vector causes the interrupt request to be de-asserted, which causes the next highest priority pending interrupt request to become the highest priority pending interrupt request. As a result, a new vector is presented for the next read by the DSP.

Abstract: A method and apparatus for improving the successful transmission of facsimile data over a wireless communication channel is provided comprising a facsimile machine, a wireless transceiver and a connector interfacing therebetween. The facsimile machine detects an interface with the wireless transceiver and notifies the facsimile machine of a wireless communication channel through which facsimile data will traverse. The facsimile machine, in conjunction with the wireless transceiver, establishes a wireless communication channel according to an initial data transfer rate corresponding with the capability of the wireless transceiver or known communication channel conditions. The facsimile machine then exchanges facsimile data over the wireless communication channel and a receiving facsimile machine evaluates the facsimile data to detect errors injected through the wireless communication channel.
