Oleg Sergeev Homepage on 8052.com Welcome to my homepage Here you can see and download useful programs, schemes, suggestions etc about C51 serie MCU. Conversion subroutines Convert 24-bit binary to 4-byte BCD METHOD: Gorner algorithm SIZE: 59 / 100 bytes TIME: 689...1073 / 18...1131(max) machine cycles Convert 24-bit binary to 4-byte BCD METHOD: Adding of nibble decimal weight precalculated in tables SIZE: 404 bytes TIME: 38...179(max) machine cycles Convert 24-bit binary to 4-byte BCD METHOD: Adding of byte decimal weight precalculated in tables SIZE: 2379 bytes TIME: 29...76(max) machine cycles CRC subroutines CRC-16 with 0x1021 polynome METHOD: Direct calculation SIZE: 51 bytes TIME: approx. 132 machine cycles per each byte CRC-16 with 0x1021 polynome METHOD: Table realization SIZE: 560 bytes TIME: approx. 28 machine cycles per each byte Good luck with stuff above!
