(for example, assume that the program counter and the address
registers are 16 bits wide) and having a 16-bit data bus.
a. What is the maximum memory address space that the
processor can access directly if it is connected to a "16-bit
memory"?
b. What is the maximum memory address space that the
processor can access directly if it is connected to an "8-bit
memory"?
c. What architectural features will allow this microprocessor to
access a separate "I/O space"?
d. If an input and an output instruction can specify an 8-bit I/O
port number, how many 8-bit I/O ports can the microprocessor
support? How many 16-bit I/O ports? Explain.

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?
Suppose you have a RISC machine with a 2.7 GHz clock (i.e., the clock ticks 2.7 billion times per second). This particular computer uses an instruction cache, a data cache, an operand fetch unit, and an operand store unit. The instruction set includes simple instructions with the following timings: SET reg, immed ; 3 clock cycles LOAD reg, mem ; 4 clock cycles ADD reg, reg ; 3 clock cycles ADD reg, immed ; 2 clock cycles LOOP _LabelName ; 8 clock cycles Assume that the following code fragment is used to sum the element ofa numeric array. SET reg1, O SET reg2, MAX_SIZE ;initialize loop counter SET reg3, @list ;initialize array pointer ProcessArray: LOAD reg4, [reg3] ;fetch current list element ADD reg1, reg4 ADD reg3, 4 LOOP _ProcessArray ;auto-decrement reg2, jump to more if reg2 # 0 If the initialization code has already executed (i.e. the SET instructions have already finished execution) how many array elements can be processed in 4.4 milliseconds (ms)?

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. How many bits can be used for the memory address?
