1. If an MPU is capable of addressing 128 K-byte of memory, calculate the size of its address bus. 2. PIC18F MCU has a 12-bit address bus for its data memory. If we increase the size to 14 bits, what is the size of the data memory? 3. What is an I/O port and what is the size of the address of an I/O port in the PIC18MCU?

Step 1
To calculate the size of the address bus, we need to determine the number of addressable locations. Since the MPU is capable of addressing 128 K-byte of memory, we can convert this to bits by multiplying it by 1024 (to convert from K-byte to byte) and then by 8 Show more…

The memory unit of a computer has $256 \mathrm{k}$ words of 32 -bits each. The computer has an instruction format with four fields: 1. An operation field 2. A mode field to specify one of 8 addressing modes 3. A Register address field to specify one of 120 processor registers. 4. A memory address. Then what is the number of bits in each field respectively if the instruction is in one memory word? (A) $4,3,7,18$ (B) $3,4,7,18$ (C) $2,1,6,23$ (D) $3,7,4,18$
