Study Notes
Computer Architecture and Instruction Fields
- The common bus system instruction fields include the OP-code, Address, and Mode fields that specify the operation to be performed, memory addresses, and address interpretation, respectively.
- The number of address fields in the instruction format depends on the internal organization of the CPU.
- The three most common CPU organizations are single accumulator organization, general register organization, and stack organization.
- Two-address instructions involve OP, AD1, and AD2 fields, while three-address instructions involve OP, AD1, AD2, and AD3 fields.
- One-address instructions utilize an implied AC register for all data manipulation.
- Zero-address instructions are found in stack-organized computers and involve operations like PUSH, ADD, MUL, and POP.
- Addressing modes specify rules for interpreting or modifying the address field of the instruction before the operand is referenced.
- The types of addressing modes include implied mode, immediate mode, register mode, register indirect mode, autoincrement or autodecrement mode, direct address mode, indirect addressing mode, and relative addressing modes.
- Immediate mode specifies the operand itself, while register mode specifies the register address for the operand.
- Autoincrement or autodecrement mode automatically increments or decrements the value in the register when used to access memory.
- Indirect addressing mode specifies the address of a memory location containing the address of the operand, allowing large physical memory to be addressed with a relatively small number of bits.
- Relative addressing modes include PC Relative Addressing Mode, Indexed Addressing Mode, and Base Register Addressing Mode, each depending on a designated register to calculate the address of the operand.
