Today, when I review the code, I found this macro definition:#define COLOR_TO_MTK_COLOR_SIMUL ((color >>) 0x1f) | (((color) >> Ten 0x3f) | ((color) >> 3) 0x1f)Do you know what this macro is for?After careful analysis, the original is to realize the conversion of RGB888 to RGB565, access to relevant information, found that there is a network of cattle writing Dongdong, here and you share.Talk about quantitative compression and quantification compensation.In color format conversion, often encou

optimizations can be high or low, and even improve performance by 20% in some tests that use the latest CPUs and the "/g7" option. Using the "/g7" option does not mean that the generated code can only run on the Intel Pentium 4 and AMD Athlon processors. The code can still run on older CPUs, but there may be a "small penalty" for performance. In addition, we have observed that some programs that run on AMD Athlon after using "/g7" are slower than Intel Pentium 4. When the "/GX" option is not

Bandwidth issues for NVIDIA GPU on HP Xeon 55xx servers But through the SDK bandwidth test, the numerical value is rather strange. Host-> device up to 3gb/s, device-> host highest only 3.2gb/s, which is the same as the PCI Express Gen 2.0 5-6gb/s data is relatively large.

Simply enter "=b6+1" in cell C6, enter "5th review" in the D5 cell, enter "=b6+2" in the D6 cell, enter "6th memory" in the E5 cell, enter "E6" in the B6+4 cell, and so on.
