A read/write type memory will be designed for a microprocessor with 16 bit address bus.. Memory chips will be 1K type. Write down bitwise memory addresses for each chip and determine address bits for S0=, S1= and I0=, I1=, I2= and I3= for which memory chip. Draw the full system architecture (CPU-Memory-Decoder-Buses). Write your name on, Student Id and put signature on the paper and take full picture If your last digit of your Student ID is 0, 2,5 then memory range $1C00H-27FFH If your last digit of your Student ID is 1, 3, 6, 9 then memory range $2400H-33FFH If your last digit of your Student ID is 4, 7 , 8 then memory range $3800H-43FFH LAST DİGİT = 9

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 cycles

A digital computer has a memory unit with 24 bits per word. The instruction set consists of 150 different operations. All instructions have an operation code part (opcode) and an address part (allowing for only one address, similar to Marie). Each instruction is stored in one word of memory. a) How many bits are needed for the opcode? b) How many bits are left for the address part of the instruction? c) What is the maximum allowable size for memory?
