Abstract:
1. A system of cascaded devices, comprising: a first device having a first input for receiving a request signal from a first source, a second input for receiving a first reply signal from said first source, a first output for outputting said request signal, and a second output for outputting a second reply signal; a first buffer having a first programmable buffer stage depth comprising a first number of buffer stages, wherein when the first number of buffer stages is greater than zero, the first buffer is coupled to said first device for receiving said outputted request signal and when the first number of buffer stages is zero, the first buffer is not coupled to said first device and does not receive said outputted request signal; and a second buffer having a second programmable buffer stage depth comprising a second number of buffer stages, wherein when the second number of buffer stages is greater than zero, the second buffer is coupled to said first device for receiving said second reply signal and when the second number of buffer stages is zero, the second buffer is not coupled to said first device and does not receive said second reply signal.
