Question: Four of the 32 pages of the memory of Problem must be accessible at any time. Four auxiliary 5-bit registers, each containing a page address, are used for this purpose. The processor outputs a 10-bit address, the most significant two bits of which select one of the auxiliary registers and the least significant eight bits select a word within a page, the page number obtained from the selected auxiliary register. Design the circuit to convert the 10-bit address output by the processor into the 13-bit address required.
Problem: An 8K memory is divided into 32 equal-size blocks (or pages) of 256 words each. The address bits are then grouped into two fields: the page number and the number of the memory word within a page. Draw the memory, MAR, and MBR configurations.
