| lkcl | programmerjake, we've had word that people within OPF are slightly freaking out at how large SV is | 12:52 |
| lkcl | ironically i've been warning the OPF precisely and exactly of the fact that it was going to be large, starting over 18 months ago, and continuing to warn them that this prediction has come about, repeatedly | 12:53 |
| lkcl | so that they're not... surprised | 12:53 |
| lkcl | the last thing we need is for the OPF ISA WG Members to start to get pissed off and to begin resenting reading what we're proposing because it begins to cause "damage" to the ISA | 12:58 |
| lkcl | and the more exceptions that interact with the Scalar ISA, the more they're going to get pissed off | 12:58 |
| lkcl | they don't *have* to accept what we're planning to propose. we're already kinda twisting their arm somewhat because of the high-profile mass-volume status of what we're doing | 12:59 |
| lkcl | as in: we _could_ use the get-out-of-jail-free card (EXT022 Sandbox for Custom "private" - non-authorised - Extensions) but the consequences of that, long-term, are something they're already keenly aware of | 13:00 |
| lkcl | consequently, that's a trump-card that can only be played a certain number of times | 13:01 |
| lkcl | i realise that SV is mind-bending. it's a multi-dimensional ISA | 13:10 |
| lkcl | as in: it's literally best to think of it in terms of multiple dimensions | 13:11 |
| lkcl | * operation | 13:11 |
| lkcl | * operation width(s) | 13:11 |
| lkcl | * vectorisation | 13:11 |
| lkcl | * program counter advancement | 13:12 |
| lkcl | (those last two can be swapped priority to give either Horizontal-First or Vertical-First) | 13:12 |
| lkcl | * saturation-augmentation | 13:12 |
| lkcl | * re-mapping | 13:12 |
| lkcl | all of those are smashed together in a single linear 1D "set of instructions" in both a traditional SIMD and traditional Vector ISA | 13:13 |
| lkcl | whereas for SV those concepts are applied near-orthogonally, almost completely independently of each other. | 13:14 |
| sadoon[m] | <lkcl> "sadoon, that's really appreciate..." <- It's the least I can do | 13:29 |
| lkcl | cesar, if you can get gram working that would be fantastic. it's quite significant as it would also get versa_ecp5 and arctic_tern working | 23:36 |
| cesar | Sure! | 23:43 |
