ORI 455H; Rotate Instructions RLC WebThe first commercially successful microprocessor is the 8085 microprocessor by Intel. This microprocessor was mainly developed to eliminate the drawbacks of 8080 architecture. 8085 microprocessor is an 8-bit microprocessor because at a time it works on 8-bits and the technology used to design this processor is N-MOS technology.
WebJun 27, 2024 · Microprocessor 8085. In 8085 Instruction set, depending upon one of the flag bit values (excluding AC flag bit), the conditional call instructions will branch to a subroutine. The branch takes place based on the value of Cy flag, Z flag, P flag, or S flag. There is no call instruction based on the value of AC (Auxiliary Carry) flag bit. 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.
