- Assume that the microprocessor can directly address 1M with a and 8 data pins. The maximum RAM system can design by using the following RAM chips is. Size of RAM chip Number of Chips 2K × 4 6 4K × 4 7 1k × 4 512 × 8 5 10 a. 27k × 8 b. 26k × 8 c. None of them d. 24k × 8 e. 25k × 82. This question is about Digital Logic and Address DecodingA computer is being designed using a microprocessor with a 16-bit address bus (A0—A15, where A0 is the least significant bit). The 64K address space is to be split betweenand allocated to RAM, ROM and I/O hardware as follows:Address Range (hex) Contains Select Signal0x0000 — 0x1FFF Main RAM RAMCS0x8000 — 0x9FFF Video RAM VRAMCS0xB000 — 0xBFFF I/O hardware IOCS0xC000 — 0xCFFF BASIC ROM BROMCS0xF000 — 0xFFFF OS ROM OSROMCSThe rest of the address space is unused.Note: As with many computer systems, it its only necessary to decode addresses to sufficiently identify each of the sections above uniquely. It is acceptable for some parts to be decodeable by more than one address provided these extra addresses do not overlap any of the other specified address ranges. Using a combination of AND, OR and NOT gates and the signals (A12 — A15) that contain the top four bits of the address in binary form: a. Derive the equation for a logic…We want to build a byte organized main memory of 8 GB for a 32-bit CPU architecture composed ofbyte organized memory modules of 30-bit address and 8-bit data buses each.a) Draw the interface of the main memory by clearly indicating the widths of the buses.b) How many memory modules would be necessary to build the memory system?c) Design the main memory internal organization built out of the above memory modules (usemultiplexers and/or decoders as needed) by clearly indicating the widths of the used bussesd) Can we use this memory system as RAM for the CPU in Problem 1? Explain your answer.

- A microprocessor has an increment memory direct instruction, which adds 1 to the value in a memory location. The instruction has five stages: fetch opcode(four bus clock cycles),fetch operand address (three cycles), fetch operand (three cycles) add 1 to operand (three cycles), and store operand (three cycles). a. By what amount (in percent) will the duration of the instruction increase if we have to insert two bus wait states in each memory read and memory write operation? b. repeat assuming that the increment operation takes 13 cycles instead of 3 cyclesa) A block-set associative cache memory consists of 128 blocks divided into four block sets.
