CpE414a

3. It is used to generate interrupts signals which tells the CPU to pause its current task and start executing another set of predefined activities.
4. A circuitry needed to perform the arithmetic, logic, and shift operations demanded by the instruction set.
8. These are extremely fast memory locations within the CPU that are used for holding data, addresses and instructions during processing the instruction.
9. These are registers that can store either address or the data but not both.
10. A control unit that generates control signals with the help of stored microinstructions.
12. A memory location where microprograms are stored.
13. A technique in which two or more independent CPU are placed in a single IC in order to increase performance.
14. A section of CPU that contains the control unit.
15. Also known as out-bus used for transferring data out of the registers.
16. Also known as in-bus used for moving data into registers.

1. A process where multiple instructions are overlapped from the processor during execution.
2. These are registers that can store both data and addresses at a same time.
5. A control unit that generates the control signals needed for the processor using logic circuits.
6. A section of CPU that contains the registers and the ALU.
7. This used to transfer data from memory to an I/O device directly without using the CPU.
11. The entity responsible for fetching, decoding, and executing instruction from the memory.
