Intel 1486 has A31 - A2 address pins as well as --BE3, -BE2, -BE1, and --BE0 byte enable pins. It has 32 data lines: D31 - DO. Assume that we want to connect i486 to a memory system M that is built with a number of LY62W20488 memory chips, each with 2M x 8-bit wide data. Answer the following three questions. 1. How many bytes of memory should the memory system M have (The capacity of the memory system)?2. How many hardware-page selection bits does this memory system M have? In other words, how many upper address lines of i486 should be used for choosing each hardware page of memory chips?3. How many memory chips is needed to construct this memory system M?
