| lkcl | twin +/- FMAC is working, that's phase 2 of the DCT/DFT augmentations | 19:12 |
|---|---|---|
| programmerjake | yay! | 22:28 |
| lkcl | it's quite fascinating, how many uses FFT/DCT/DFT has, and really quite scary the amount of code and assembler needed | 23:14 |
| lkcl | the wikipedia page for Cooley-Tukey does warn though that solving the bit-reverse LOAD isn't the full picture | 23:14 |
| lkcl | there's also the fact that the L1/L2 caches get hit by "distributed" data | 23:15 |
| lkcl | and of course, it's all on power-of-two boundaries | 23:15 |
| lkcl | which means that there's the risk of hitting the exact same cache line for the array data | 23:16 |
| lkcl | hilarously, finding efficient simple *scalar* algorithms is challenging | 23:17 |
