In practice, any single monolitic function which does the work can + * be split into two parts in any arbitrary way without affecting correctness. + * + * There is one special trick here too.

Using the above two + * macros, the work can be done right. But now we want to optimize + * it a bit. ARM Cortex-A8 is an in-order core, and benefits really + * a lot from good code scheduling and software pipelining. + * + * Let's construct some code, which will run in the core main loop. + * Some pseudo-code of the main loop will look like this: + * head + * while (...) { + * tail + * head + * } + * tail + * + * It may look a bit weird, but this setup allows to hide instruction + * latencies better and also utilize dual-issue capability more + * efficiently (make pairs of load-store and ALU instructions). + * + * So what we need now is a '*_tail_head' macro, which will be used + * in the core main loop. A trivial straightforward implementation + * of this macro would look like this: + * + * pixman_composite_over_8888_0565_process_pixblock_tail + * vst1.16 {d28, d29}, [DST_W, :128]! + * vld1.16 {d4, d5}, [DST_R, :128]! + * vld4.32 {d0, d1, d2, d3}, [SRC]! + * pixman_composite_over_8888_0565_process_pixblock_head + * cache_preload 8, 8 + * + * Now it also got some VLD/VST instructions. We simply can't move from + * processing one block of pixels to the other one with just arithmetics. + * The previously processed data needs to be written to memory and new + * data needs to be fetched. Fortunately, this main loop does not deal + * with partial leading/trailing pixels and can load/store a full block + * of pixels in a bulk. Additionally, destination buffer is already + * 16 bytes aligned here (which is good for performance). + * + * New things here are DST_R, DST_W, SRC and MASK identifiers. These + * are the aliases for ARM registers which are used as pointers for + * accessing data. We maintain separate pointers for reading and writing + * destination buffer (DST_R and DST_W). + * + * Another new thing is 'cache_preload' macro. It is used for prefetching + * data into CPU L2 cache and improve performance when dealing with large + * images which are far larger than cache size. It uses one argument + * (actually two, but they need to be the same here) - number of pixels + * in a block. Looking into 'pixman-arm-neon-asm.h' can provide some + * details about this macro. Moreover, if good performance is needed + * the code from this macro needs to be copied into '*_tail_head' macro + * and mixed with the rest of code for optimal instructions scheduling. + * We are actually doing it below. + * + * Now after all the explanations, here is the optimized code. + * Different instruction streams (originaling from '*_head', '*_tail' + * and 'cache_preload' macro) use different indentation levels for + * better readability.

The main idea is that + * cache preload logic is mostly independent from the rest of pixels + * processing code. It starts at the top left pixel and moves forward + * across pixels and can jump across scanlines. Prefetch distance is + * handled in an 'incremental' way: it starts from 0 and advances to the + * optimal distance over time. After reaching optimal prefetch distance, + * it is kept constant. There are some checks which prevent prefetching + * unneeded pixel lines below the image (but it still can prefetch a bit + * more data on the right side of the image - not a big issue and may + * be actually helpful when rendering text glyphs). Additional trick is + * the use of LDR instruction for prefetch instead of PLD when moving to + * the next line, the point is that we have a high chance of getting TLB + * miss in this case, and PLD would be useless. + * + * This sounds like it may introduce a noticeable overhead (when working with + * fully cached data). But in reality, due to having a separate pipeline and + * instruction queue for NEON unit in ARM Cortex-A8, normal ARM code can + * execute simultaneously with NEON and be completely shadowed by it. Thus + * we get no performance overhead at all (*). This looks like a very nice + * feature of Cortex-A8, if used wisely. We don't have a hardware prefetcher, + * but still can implement some rather advanced prefetch logic in sofware + * for almost zero cost! + * + * (*) The overhead of the prefetcher is visible when running some trivial + * pixels processing like simple copy.
