WebWhen the system starts, cs = f000h, IP = fff0h, that is, execution starts from the address ffff0h. This region belongs to the system BIOS. (F000: fff0) = ea5be000f0 (which is the hexadecimal representation of the JMP f000: e05b command). It immediately jumps to the BIOS initialization program and starts the system startup process. WebMay 31, 2024 · Algorithm – The instruction MOV B, C is of 1 byte; therefore the complete instruction will be stored in a single memory address. For example: 2000: MOV B, C. Only opcode fetching is required for this instruction and thus we need 4 T states for the timing diagram. For the opcode fetch the IO/M (low active) = 0, S1 = 1 and S0 = 1.
