MAR, MDR, Cache, RAM, Clock Speed and CPU Cores
Flashcards do conjunto (6)
- 1MARMemory Address Register holds the address of the current instruction that is to be fetched from memory, or the address in memory to which data is to be transferred
- 2MDRMemory Data Register holds the contents found at the address held in the MAR, or data which is to be transferred to primary memory
- 3CacheCache memory is a type of high-speed RAM which is built into the processor. Data can be transferred to and from cache memory more quickly than from RAM. As a result, cache memory is used to temporarily hold data and instructions that the processor is likely to reuse.
- 4RAMRandom access memory is volatile primary memory. The contents of RAM can be changed at any time, simply by overwriting them with other data and/or instructions.
- 5Clock Speedthe operating speed of a computer or its microprocessor, expressed in cycles per second
- 6CoresA processing unit within a CPU is known as a core. Each core is capable of fetching, decoding and executing its own instructions. The more cores a CPU has, the greater the number of instructions it can process in a given space of time. Many modern CPUs are dual or quad core processors
