Abstract
A bus arbiter that ensures high priority transfers complete and allows high-priority data transfers with specific latency requirements, such as 802.11 requirements, to be prioritized above data transfers with lower latency requirements. As an example, the arbiter closely manages all transactions and guarantees sufficient latencies by pre-empting lower-priority data transfers with higher priority data transfers. All devices on the bus are configured with a latency timer setting of zero or a non-zero value which guarantees required data transfer latencies are met which means that any device will terminate bus-master transfers quickly upon the bus grant signal being de-asserted. To ensure a transfer completes, bus grant for the priority transfer is asserted until entire data transfer completion is imminent, enabling transfers, such as high priority transfers, to complete uninterrupted.
