Study Notes
Evaluating Expressions
- To evaluate the expression A * B + C * D, the necessary instructions in a single accumulator processor are: load, multiply, add, and store.
- A zero operands program format is required to evaluate the expression A * B + C * D.
Instruction Format
- Four operands are involved in the instruction format needed to evaluate A * B + C * D.
- In a zero operands-instruction format, five instructions are needed to evaluate the expression A * B + C * D.
Cache Memory
- Direct mapping, associative mapping, and set-associative mapping are typically used in Cache memory.
Bus Arbitration
- The key purpose of Bus arbitration techniques in a computer system is to manage access to the shared bus among multiple devices.
- The Bus arbitration technique that involves granting priority to multiple devices based on their predefined levels is fixed priority arbitration.
Instruction Execution
- The essential instructions for executing the operation ADD(R3), R1 are: load, add, and store.
Processor Operations
- Division is NOT directly supported by the processor described in the text.
Instruction Format Comparison
- A key difference between a Two operands-instruction format and a Three operands-instruction format is that the latter allows for more flexibility in specifying the source and destination operands.
Interrupt Handling
- A nested interrupt diagram best represents the concept of interrupt nesting in handling multiple devices.
Computer-IO Device Communication
- A fundamental hardware component required to establish communication between a computer and I/O Devices is an interface.
