Essay: The Purpose of Registers in Memory

Sample Essay

Registers also proved to be used for quick access holding frequently used values which are scalar. The main memory or RAM which is slower in magnitude as compared to registers with the order of two almost. This is the reason why it needed to overcome by-value operations with by-reference operations using registers in order to trim down the number of memory operations in a program.

Cache was incorporated in memory to pass the data between memory and registers effectively by acting as buffers. This act diminishes the impact of slow memory speeds. The registers apart from giving complicated program code also provides the shorter access time and shorter instruction coding because it mainly requires direct operations, being accessed with direct address. So we have the merits and also the demerits of caches and registers but they both are amongst those foundations which helped processors in functioning with speed, accuracy, and stability (Postiff).
