During the operation of a central processing unit (CPU) operating under the Von Neumann architecture, dedicated registers are utilized to manage the flow of instructions and data.
Identify the two specific CPU registers whose primary function is to store memory addresses (rather than instruction opcodes or raw data values) during the Fetch-Decode-Execute (FDE) cycle.
Practise Edexcel GCSE Computer Science Hardware with exam-style questions for GCSE Computer Science. 97 questions covering Von Neumann architecture and FDE cycle, Secondary storage devices, and Embedded systems, matched to the Edexcel GCSE Computer Science (1CP2) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
