There are 74 instructions in the 8085 microprocessor.
There are 74 instructions in the 8085 microprocessor.
The 8085 is an 8 bit processor, so its word length is 8 bits.
The NOP instruction is a no-operation instruction. It does nothing to the state of the machine, except to use some time. In the case of the 8085, it uses four clock cycles plus however many wait states are need to access the NOP instruction from memory.
The instruction MOV A in assembly language typically requires 1 byte. This instruction is used to move data into the accumulator register (A) from another register or memory location, but the specific number of bytes may depend on the context, such as the source operand being specified. In many assembly languages, the instruction itself is one byte, while additional bytes may be needed for operands.
there are 74 instruction sets in the 8085 up which consist of 246 bit pattern.
RET instruction needs 3 machine cycles. One to fetch and decode the instruction(4 T states), and two more machine cycles(i.e. 2*3=6 T states) to read two bytes from the stack(stack is exterior to microprocessor, stack is in R/W memory, so to exchange data with stack needs machine cycles). Thus, RET instruction needs total 3 machine cycles and 10 T-states.
when conditional jump instruction is executed it has 10 m/c cycles bt when nt executed it has 7 m/c cycles....while unconditional jump instruction has 10 m/c cycles...
The instruction IN 84H in the 8085 microprocessor requires 5 machine cycles to complete. This includes 1 opcode fetch cycle and 4 memory read cycles. The opcode fetch retrieves the instruction from memory, while the read cycles are used to read the data from the specified input port.
The 8085 has a 16 bit address bus.
The major difference between the 8085 and the 8086/8088 is that the 8085 is an 8 bit computer, and the 8086/8088 is a 16 bit computer.
