| * Implementation of pixman_composite_over_8888_0565_asm_neon |
| * |
| * This function takes a8r8g8b8 source buffer, r5g6b5 destination buffer and |
| * performs OVER compositing operation. Function fast_composite_over_8888_0565 |
| * from pixman-fast-path.c does the same in C and can be used as a reference. |
| * |
| * First we need to have some NEON assembly code which can do the actual |
| * operation on the pixels and provide it to the template macro. |
| * |
| * Template macro quite conveniently takes care of emitting all the necessary |
| * code for memory reading and writing (including quite tricky cases of |
| * handling unaligned leading/trailing pixels), so we only need to deal with |
| * the data in NEON registers. |
| * |
| * NEON registers allocation in general is recommented to be the following: |
| * d0, d1, d2, d3 - contain loaded source pixel data |
| * d4, d5, d6, d7 - contain loaded destination pixels (if they are needed) |
| * d24, d25, d26, d27 - contain loading mask pixel data (if mask is used) |
| * d28, d29, d30, d31 - place for storing the result (destination pixels) |
| * |
| * As can be seen above, four 64-bit NEON registers are used for keeping |
| * intermediate pixel data and up to 8 pixels can be processed in one step |
| * for 32bpp formats (16 pixels for 16bpp, 32 pixels for 8bpp). |
| * |
| * This particular function uses the following registers allocation: |
| * d0, d1, d2, d3 - contain loaded source pixel data |
| * d4, d5 - contain loaded destination pixels (they are needed) |
| * d28, d29 - place for storing the result (destination pixels) |
| */ |
| |
| /* |
| * Step one. We need to have some code to do some arithmetics on pixel data. |
| * This is implemented as a pair of macros: '*_head' and '*_tail'. When used |
| * back-to-back, they take pixel data from {d0, d1, d2, d3} and {d4, d5}, |
| * perform all the needed calculations and write the result to {d28, d29}. |
| * The rationale for having two macros and not just one will be explained |
| * later. 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. Common template macro can optionally |
| * make our life a bit easier by doing R, G, B, A color components |
| * deinterleaving for 32bpp pixel formats (and this feature is used in |
| * 'pixman_composite_over_8888_0565_asm_neon' function). So it means that |
| * instead of having 8 packed pixels in {d0, d1, d2, d3} registers, we |
| * actually use d0 register for blue channel (a vector of eight 8-bit |
| * values), d1 register for green, d2 for red and d3 for alpha. This |
| * simple conversion can be also done with a few NEON instructions: |
| * |
| * Packed to planar conversion: |
| * vuzp.8 d0, d1 |
| * vuzp.8 d2, d3 |
| * vuzp.8 d1, d3 |
| * vuzp.8 d0, d2 |
| * |
| * Planar to packed conversion: |
| * vzip.8 d0, d2 |
| * vzip.8 d1, d3 |
| * vzip.8 d2, d3 |
| * vzip.8 d0, d1 |
| * |
| * But pixel can be loaded directly in planar format using VLD4.8 NEON |
| * instruction. It is 1 cycle slower than VLD1.32, so this is not always |
| * desirable, that's why deinterleaving is optional. |
| * |
| * But anyway, here is the code: |
| */ |

| /* |
| * OK, now we got almost everything that we need. 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. Actually taking the code from one of these |
| * indentation levels and ignoring a few VLD/VST instructions would |
| * result in exactly the code from '*_head', '*_tail' or 'cache_preload' |
| * macro! |

| * And now the final part. We are using 'generate_composite_function' macro |
| * to put all the stuff together. We are specifying the name of the function |
| * which we want to get, number of bits per pixel for the source, mask and |
| * destination (0 if unused, like mask in this case). Next come some bit |
| * flags: |
| * FLAG_DST_READWRITE - tells that the destination buffer is both read |
| * and written, for write-only buffer we would use |
| * FLAG_DST_WRITEONLY flag instead |
| * FLAG_DEINTERLEAVE_32BPP - tells that we prefer to work with planar data |
| * and separate color channels for 32bpp format. |
| * The next things are: |
| * - the number of pixels processed per iteration (8 in this case, because |
| * that's the maximum what can fit into four 64-bit NEON registers). |
| * - prefetch distance, measured in pixel blocks. In this case it is 5 times |
| * by 8 pixels. That would be 40 pixels, or up to 160 bytes. Optimal |
| * prefetch distance can be selected by running some benchmarks. |
| * |
| * After that we specify some macros, these are 'default_init', |
| * 'default_cleanup' here which are empty (but it is possible to have custom |
| * init/cleanup macros to be able to save/restore some extra NEON registers |
