WebThe checksum loop is unrolled which makes the code harder to reason about while providing small performance improvement: - max eeprom length is 0x80 bytes (MAX_EECODE_SIZE), that's only 0x40 iterations - checksum is only computed during pci probe(), so not very often Tested on Mojave card. WebMar 14, 2013 · Sorted by: 1. I'm not sure what BCC is, so I'll just assume you want the XOR of the array. If this data is constant, you can just calculate the XOR once and make it a constant too: // 0x02 ^ 0x06 ^ 0x06 ^ 0x06 ^ 0x06 ^ 0x06 = 0x04 byte result = 0x04. Otherwise, you have to do this with variables: byte result = data [0] ^ data [1] ^ data [2 ...
