* | SBC arrays and constant tables aligned at 16 byte boundary for SIMD | Siarhei Siamashka | 2009-01-16 | 1 | -1/+1 |
| | | | | | | | Most SIMD instruction sets benefit from data being naturally aligned. And even if it is not strictly required, performance is usually better with the aligned data. ARM NEON and SSE2 have different instruction variants for aligned/unaligned memory accesses. | ||||
* | SIMD-friendly variant of SBC encoder analysis filter | Siarhei Siamashka | 2009-01-16 | 1 | -0/+52 |
Added SIMD-friendly C implementation of SBC analysis filter (the structure of code had to be changed a bit and constants in the tables reordered). This code can be used as a reference for developing platform specific SIMD optimizations. These functions are put into a new file 'sbc_primitives.c', which is going to contain all the basic stuff for SBC codec. |
