Answer #1

Here, the highest 6 bits of the address are given by :

1010 01

The remaining bits can span the entire range, with each bit taking a 0 or 1.

Thus,

  • lowest address in binary = 1010 0100 0000 0000 0000 0000 0000 0000
  • highest address in binary = 1010 0111 1111 1111 1111 1111 1111 1111

which is equivalent to the hex range :

0xA4000000 - 0xA7FFFFFF

    Question 20 5 pts Suppose a computer has 32-bit instructions. The instruction set consists of 64 different operations. All instructions have an opcode and two address fields (allowing for two addresses). The first of these addresses must be a register direct address, and the second must be a memory address. Expanding opcodes are not used. The machine has 16 registers. What's the size of the largest memory space that can be addressed by this computer?Assume byte addressable memory.

    Suppose that we have a computer system using 32-bit logical address and 46–bit physical address. It also uses paging for memory management with a single-level page table organization. The page size is 4K bytes and each page table entry is 32 bits or 4 bytes in size. Calculate the number of bits in each field in the logical address, the size in bytes of the page table, and the number of frames.
