| stekern | olofk: still re deasserting stb, thinking some more about it, what I said yesterday that you can use the registered stb was not correct, you should just use ack to determine if there is valid data | 06:50 |
|---|---|---|
| stekern | an asserted ack should always mean that the slave has valid data | 06:51 |
| olofk | stekern: I think the problem in an incremental burst is that I can't use ack to trigger the next request | 08:58 |
| olofk | hmm.. my option of routing read requests through async failed too. For inc bursts the next address will be wrong | 09:13 |
| stekern | why not? | 09:47 |
| stekern | !stb inserts wait states, when you are done waiting you assert stb and on the next ack you advance | 09:48 |
| olofk | hmm.. | 11:33 |
| olofk | I was perhaps thinking that it would be a problem is latency > 1 cycle, but in those cases, the slave will deassert ack anyway | 11:34 |
| stekern | right | 12:13 |
| iorivur | Hi, I've played with OpenRISC 1+ years ago, and now I'm backed. Is or2k hot now? What's the newest implementation, or best to play with? | 15:05 |
| wallento | hi, there is (and maybe never will be) an or2k | 15:17 |
| wallento | _but_: There have been a lot of improvements and the mor1kx is the new hot implementation | 15:17 |
| iorivur | ok thanks. well.... I forgot about... what's the meanings/positioning of orsoc and mor1k | 15:44 |
| iorivur | mor1k is core and orsoc is system implementation wasn't it? | 15:45 |
| iorivur | why IP core? How do you develop it? | 15:50 |
| wallento | orpsoc is fusesoc now, it contains more cores than mor1kx | 15:59 |
| wallento | (and everything is also multicore now) | 16:00 |
| -!- knz_ is now known as knz | 16:01 | |
| iorivur | hmm....ok, ok, i'm getting back the sense | 16:24 |
| iorivur | thanks. | 16:24 |
| olofk | Gaahh!! I still can't figure out how to make this work | 20:37 |
| olofk | Time to try the third approach | 20:59 |
| olofk | This does actually seem to work better | 22:08 |
| olofk | Yes! I'm getting there | 22:11 |
| olofk | Still hitting plenty of bugs though | 22:19 |
