ABSTRACT:
A dual bus controller includes a system bus control module connected to a local bus control module. An optional filter is also connected to the system bus control module. A plurality of programmable status registers for the local bus is connected to the local bus control module and a time dependent reset circuit is connected to both the system bus control module and the local bus control module. The dual bus controller allows simultaneous, autonomous activity with both the local bus and the system bus via the local bus and system bus control modules. The unique interaction between the local bus and system bus control modules also allow both the local bus and system bus to interact with the dual bus controller operating as a slave without any imposed speed limitations by actively resolving bus collisions and "live-lock" conditions.
