SUMMARY

The 8085 Microprocessor determines the size of an instruction through its instruction decode logic, which is specifically designed to handle multibyte instructions. When a multibyte instruction is encountered, the microprocessor performs additional byte fetches from memory to accurately decode the instruction size. This mechanism ensures that the 8085 can effectively process varying instruction lengths, enhancing its operational efficiency.

PREREQUISITES
  • Understanding of 8085 Microprocessor architecture
  • Familiarity with instruction set and encoding
  • Knowledge of memory fetch operations
  • Basic concepts of instruction decoding
NEXT STEPS
