SUMMARY

The discussion focuses on the Register Transfer Language (RTL) for the MOV A, B instruction on the 8085 microprocessor. The MOV A, B instruction transfers the contents of register B to register A. The RTL representation involves two main cycles: the opcode fetch cycle, where the opcode for MOV A, B is retrieved from memory, and the execute cycle, where the actual data transfer occurs. Understanding these cycles is crucial for grasping how the 8085 microprocessor operates during instruction execution.

PREREQUISITES
  • 8085 microprocessor architecture
  • Opcode fetch and execute cycles
  • Register Transfer Language (RTL)
  • Basic assembly language programming
NEXT STEPS
  • Study the opcode fetch cycle for the 8085 microprocessor
  • Learn about the execution cycle of MOV instructions in the 8085 architecture
  • Explore detailed CPU architecture documents from Intel or AMD
  • Practice writing RTL for other instructions on the 8085 microprocessor
USEFUL FOR

Students studying computer architecture, educators teaching microprocessor concepts, and anyone interested in low-level programming for the 8085 microprocessor.

I actually didnot know where to post there.

My teacher gave me assighnment and now its holiday here and cannot get clue from anybody for where to start.

Question was - Describe RTL(register transfer language) for MOV A,B in terms of
opcode fetch cycle &&& execute cycle.

I know this is moving content from register B to A. But I don't know how to go exactly with cycle asked.

Please help me.

The best place to find opcode representations is to look at any standard CPU architecture document for a common platform.

You can find these kind of documents at CPU vendor websites like Intel or AMD. Off the top of my head that's your best bet.
 
I forgot to mention , it is 8085 microprocesor
