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. -+ * -+ * 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 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. -+ * -+ * Another new thing is 'cache_preload' macro. It is used for prefetching -+ * data into CPU 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.

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.
