Abstract:
1. A system of cascaded devices, comprising: a first device having a first input for receiving a request signal, a second input for receiving a first reply signal, a first output for outputting said request signal, and a second output for outputting a second reply signal, said second reply signal being generated from operations performed in response to said request signal and from said first reply signal; at least one buffer coupled to said first device for receiving and outputting at least one of said outputted request signal and said second reply signal, said at least one buffer having a programmable associated latency; and a second device, said second device being coupled to receive the outputted request signal from the at least one buffer and the second reply signal from the first device when said second device has a lower latency than said first device, or said second device being coupled to receive the outputted second reply signal from the at least one buffer and the request signal from the first device when said second device has a higher latency than said first device, said at least one buffer being configured to equate the latency of said first device with the latency of said second device.
