Abstract
Buffers of programmable depths are used in the instruction and reply paths of cascaded devices to account for possible differences in latencies between the devices. The buffers may be enabled or bypassed such that the alignment of instruction and result may be performed at the boundaries between separate groups of devices having different instruction latencies.

1-27. (canceled)
A cascaded system, comprising:
- a first device having a first latency;
- a second device having a second latency different from said first latency;
- and
- at least one buffer coupled between outputs of said first device and inputs of said second device, said at least one buffer being programmed to transfer signals on the outputs to the inputs by substantially equating said first and said second latencies.

32-38. (canceled)
A processor system, comprising:
- a first device having a first latency;
- a second device having a second latency different from said first latency;
- and
- at least one buffer coupled between outputs of said first device and inputs of said second device, said at least one buffer being programmed to transfer signals on the outputs to the inputs by substantially equating said first and said second latencies.
