Across
  1. 4. The processing logic of a CPU that is manufactured on a silicon wafer containing millions or billions of transistors.
  2. 9. A CPU design that permits the processor to operate on one instruction at the same time it is fetching one or more subsequent instructions from the operating system or application.
  3. 10. An internal communications pathway that carries data between the CPU and memory locations.
  4. 11. A storage location associated with an I/O device that data can be read from and written to; a temporary holding location in a CPU where data must be placed before the CPU can use it.
  5. 12. is the chip that performs the actual computational and logic work.
  6. 17. The description of the internal circuitry of a CPU that defines characteristics such as the technology used to create the chip, the supported instruction set, and the bit size.
  7. 19. The part of a processor used to read and execute instructions
  8. 20. A computer program that takes a high-level language like C++ or Java and turns it into assembly code that is executed by the CPU.
Down
  1. 1. A small program inside a CISC CPU that must interpret and execute each instruction.
  2. 2. An internal communications pathway inside a computer that specifies the source and target address for memory reads and writes.
  3. 3. The smallest piece of computer code that can be independently scheduled for execution
  4. 5. The computer hardware design that includes the processor (CPU) and communication routes between the CPU and the hardware it manages, such as memory and disk storage
  5. 6. Are modern processors used in business system.
  6. 7. A computer that uses more than one CPU.
  7. 8. The numeric code read by the CPU that represents a particular machine instruction.
  8. 13. A memory address that a CPU begins reading from whenever the CPU receives a reset signal, such as when power is first applied or someone presses the reset button on a computer.
  9. 14. processor contains two cores and a quad-core processor has four.
  10. 15. computers have one such chip and are referred to as single-processor computers.
  11. 16. A path or channel between a computer’s CPU and the devices it manages, such as memory and I/O devices
  12. 18. Special computer memory that temporarily stores data used by the CPU. Cache memory is physically close to the CPU and is faster than standard system memory, enabling faster retrieval and processing time.
