Is fetch decode execute cycle is used in coding?
No. Fetch-decode-execute is a machine state time paradigm, not a philosophy used in coding.
What is the fetch-decode-cycle on a computer?
when we execute a program, the starting address is loaded in the program counter. Then for each instruction the processor goes through fetch-decode-execute states. At the fetch state the instruction code is fetched then decoded to understand what exactly has to be done. Then finally it executes that instruction. This process goes on till it reaches the end of the program.
How 8085 timing diagram works based on each instruction?
Each instruction requires specific time for the execution of instruction and this time is called instruction cycle. Each instruction cycle consists 1 to 5 machine cycle -- opcode fetch, memory read, memory write, IO read, IO write and each machine cycle consist 3 to 6 T - states. Time required to execute 1 T-state = 1/ operating frequency of 8085 Microprocessor for example operating frequency = 2MHz then time required to execute 1 T-state = 0.5 uSec example: Calculate time required to execute instruction MOV C, A sol: This instruction has one machine cycle i.e. opcode fetch (In any instruction 1st cycle is always opcode fetch and opcode fetch consists 4 to 6 T state depend on the operation of particular instruction) so to execute MOV C, A required 4T states so time required to execute this instruction is 4*0.5usec = 2usec any other queries pls contect: nileshbahadure2000@yahoo.co.in example:Calculate the time required to execute LXI H,2000H sol:Here we have to draw opcode fetch and two memory reads as two bytes 00H and 20H have to be read from memory. i.e, opcode fetch+Memory reads *2(bytes address) =4+3+3 so to execute LXI H,2000H,the required T-states is 10T and time is 10*0.5usec=5usec
What is a wait state?
A wait state occurs when a processor is unable to execute its next instruction due to the unavailability of required resources, such as data or memory. This can happen when the processor is waiting for inputs from external devices or waiting for data to be loaded from memory. During a wait state, the processor is idle until it can proceed with its operations.
What state is the show Fetch in?
Massachusetts
T state in op-code fetch of 8085?
There are four T states during op-code fetch in the 8085. T1 is the ALE state, where the address is emitted and the RD- line goes true; TWAIT is zero or more wait states based on READY; T2 is the middle of the fetch, and the internal strobing of the op-code; T3 is the completion of the fetch and stabilization of the bus signals; and T4 is the internal processing cycle.
