shared expertise through open source, ya love to see it

I'm thinking about that AXI burster I've decided to make. So far I haven't written any HDL, but I think it should work like this:

It has a FIFO, and presents only the first address if they are incremented, which in the case of the nmigen image address generator is guaranteed when neither of the "_last" signals signals is asserted
19:24
EmilJ
This is for FIFO depth = burst length of 4 beats
19:25
EmilJ
The highlighted edges are ones I'm not sure about, it seems like the AXI spec forbids any combinatorial connections between a slave and master interface, so I can't reassert input arready in the same cycle as output arready is asserted
19:56
anuejn
hm... you shouldnt need any fifo to implement that
19:57
anuejn
because you only need to keep track of subsequent incrementing addresses (up to the max burst length)
19:57
anuejn
if you reached the max bust length or two addresses are not subsequent you issue a new bust
20:00
EmilJ
You're right - I was keeping the FIFO in case it stops being sequential but at that point I just need to burst with ARLEN=fill_level-1
20:01
EmilJ
hmm
20:19
anuejn
yup
20:19
anuejn
thats it
