Image processing using a ram and repeat read-modify-write operation

摘要: An image processing system adaptable to pattern recognition that can serve any width using a minimum of additional hardware by constructing line buffer RAM and filling the with data while repeating RMW (Read-Modify-Write) operation. To increase speed, packing (RAM) is performed on multiple-bit basis rather than bit-by-bit basis, is, number bits written into one operation increased, for example, 2, 4, or 8, so speed be increased accordingly. appropriate mask disclosed packed in buffer.
