the value of burstcount signal

Hi everyone,

I'm new to Qsys, and I have a naive question about burstcount signal:

What's the value of burstcount when the typical read and write transfer(not burst transfers) is used? Is it 1?

regards,

zhangfeng

    That is correct, to drive a signal beat transaction you post a burst count of 1. If you don't plan on using bursting then you don't need to include the burst count signal.

    Thanks for you reply.

    I did't find this point in Avalon Interface Specification, could you show me some references?

    Section 3 of the Avalon spec would be the most useful part. Unfortunately the signal table doesn't list what signals are optional anymore. Section 3.5.4 seems to provide the most useful information. If you don't need to burst then simply don't include the burst signal in your master/slave interface.
