Method and apparatus for hot swapping and bus extension without data corruption |
摘要 |
A method and apparatus for hot swapping and bus extension without data corruption. During the hot swapping of a circuit board in a bus, the bus is extended onto or retracted from the circuit board in a manner which does not corrupt the data on the bus. The extension or retraction of the bus is detected and a bus reset is asserted interrupting and preventing transactions on the bus. The bus reset is asserted for a minimum amount of time to allow the bus to stabilize after the hot swap. A bus extension/retraction detection component and a bus reset component perform these functions.
