摘要:
A low-cost, high-speed, bus-based communication system is provided that includes a master electronics card, a number of slave electronics cards, and a backplane that interconnects the master and the slave electronics cards via a serial bus, a parallel bus and some common signals for clocking and synchronization.
摘要:
The bus circuit of a master electronics card in a backplane-based communications system adaptively grants the upstream bus to the slave electronics cards by the early termination of a scheduled number of grants to a slave electronics card when the bus circuit on the master electronics card detects idle cells.
