Question

A processor has a memory address range of 00000h – 3ffffh. if the processor has a read-only memory (rom) of size 64k bytes with a starting address of 0000h, and assuming that it is mapped onto a 2-fold folding addressing scheme, determine the range, as well as the size, of the remaining memory in the processor. also, determine the number of address lines in the processor.

Answer 1

A processor has a memory address range of 00000H – 3FFFFH. If the processor has a read-only memory (ROM) of size 64k bytes with a starting address of 0000H, and assuming that it is mapped onto a 2-fold folding addressing scheme, determine the range, as well as the size, of the remaining memory in the processor. Also, determine the number of address lines in the processor.
