| promach | wallento: for lisnoc tutorial 1, why is the 'READY' signal high only after t=19ns as in http://i.imgur.com/jjLcfXO.jpg ? | 00:46 |
|---|---|---|
| wallento | promach, hi | 06:54 |
| wallento | let me check | 06:54 |
| wallento | its hardcoded | 06:57 |
| wallento | the sink doesn't transition states until the reset is deasserted, then it waits six cycles and the combinational logic uses the negative edge, that brings us to 19ns | 06:58 |
| wallento | https://github.com/TUM-LIS/lisnoc/blob/master/tutorials/tutorial_01/tutorial_01.v#L156 and https://github.com/TUM-LIS/lisnoc/blob/master/tutorials/tutorial_01/tutorial_01.v#L189 | 06:58 |
| wallento | not the most awesome coding style, but I wanted to keep it simple at that time | 06:58 |
| wallento | and great people use it. Motivates my for lesson 3 :) | 06:58 |
| promach | wallento: I am a bit confused on the line localparam FLIT_WIDTH = FLIT_DATA_WIDTH + FLIT_TYPE_WIDTH; | 07:17 |
| wallento | it defines the total flit width, which is data plus the control signals | 07:18 |
| wallento | so the actual flit has the width FLIT_DATA_WIDTH | 07:18 |
| wallento | and there are at least two extra bits with each flit: first and last | 07:18 |
| -!- Netsplit *.net <-> *.split quits: LoneTech | 07:19 | |
| wallento | so a worm looks like (1,0,D0) (0,0,D1) (0,1,D2) | 07:19 |
| -!- Netsplit over, joins: LoneTech | 07:19 | |
| promach | wallento: I do not get the purpose of 'worm' | 07:22 |
| wallento | In a NoC a worm is an indivisible unit | 07:23 |
| wallento | composed of multiple flits | 07:23 |
| wallento | it is necessary that worm don't interleave on a link because otherwise your data gets corrupted | 07:23 |
| wallento | so while there can be multiple worms in the NoC, they can only enter and leave the NoC serialized | 07:23 |
| -!- Netsplit *.net <-> *.split quits: jonmasters, mithro, Neuron1k | 14:35 | |
| -!- Netsplit over, joins: jonmasters | 14:36 | |
| wbx | shorne: hmm. is gdb or gdbserver for openrisc linux possible to cross-compile? | 18:57 |
