  1. 2. A computer architecture that has two separate areas of memory - one for instructions & one for data. Instructions and data can be accessed concurrently. Different sets of buses - one for instructions & one for data.
  2. 4. Is slower than the L1 cache but bigger in size, between 256KB and 8MB.
  3. 7. Shared between the cores in a CPU, it is the largest but slowest cache memory often between 8 and 64MB in size.
  4. 10. A CPU design that produces a complicated and expensive integrated circuit capable of performing a large variety of complex instructions. Complex instructions can be executed with few machine cycles.
  5. 11. Any modern set of disciplines that describes the functionality, the organisation and the implementation of computer systems.
  6. 13. A special purpose CPU designed to handle high volumes of small calculations, often use with graphical processing. These of formed of many cores to perform many operations in parallel.
  7. 14. Usually part of the CPU chip itself and is both the smallest and the fastest to access. Its size is often restricted to between 8 KB and 64 KB.
  8. 15. A computer architecture that has data and Instructions stored in the same format in the same RAM. Single set of buses for fetching data and instructions.
Down
  1. 1. A part of the main store between the CPU and the rest of the memory. It has extremely fast access
  2. 3. A CPU design that produces a simple, cheap integrated circuit with a basic range of machine instructions. Relies on speed as complex instructions take many machine cycles.
  3. 5. A complete processing unit within the CPU that has its own ALU, CU and registers. There can be more than one of these inside a CPU
  4. 6. A CPU consisting of two or more cores, each core can can execute multiple instructions in parallel.
  5. 8. Measured in hertz or cycles per second, it represents how many instructions per second the processor can execute.
  6. 9. A method in computing of running two or more processors (CPUs) to handle separate parts of an overall task.
  7. 12. The process of fetching an instruction whilst decoding another and executing another in order to increase the capacity of the processor.
