Question 4: There is an application that requires the hardware: an Intel 8031, a Program ROM of 8Kx8, a Data ROM of 4Kx8 for look-up tables, TWO Data RAMs of 8Kx8. The memory map of the design should be: Program ROM should start at address 0000μ. Then, the Data ROM should come above the Program ROM. Finally the Data RAMs must go to the top of the memory map. There should be no gaps between the memory addresses of the external ROMs or RAMS. A. Using logic gates, draw the pin connections of the design. Label your diagram fully. B. Calculate the address space of the ROMs and RAMs of your design. C. Show the design's address space on a memory map, starting with 0000μ at the bottom and FFFFH at the top.

A BCD number between 0 and 99 is stored in an R/W memory location called the Input Buffer (INBUF). Write a main program and a conversion subroutine (BCDBIN) to con- vert the BCD number into its equivalent binary number. Store the result in a memory lo- cation defined as the Output Buffer (OUTBUF).
Assume that an interrupt mechanism uses the hardware stack to store PC and other registers of the interrupted computations. The interrupt mechanism recognizes 4 interrupt vectors IV [1], IV [2], IV [3], IV [4] initialized by addresses of their corresponding ISR I =1..4. The elements of the hardware stack are a record R, where each field stores a specific CPU register (R.PC is the field, which stores the program counter PC and so on). The Hardware stack is manipulated using the standard stack operation Pop, Push, EmptyStack.a) Explain how the CPU detects an interrupt signal I and what actions should be taken?b) Write the initial and final sequences of instruction of a given ISR I (Transparency).c) Write the ISR4 such that whatever number of interrupted computation (in the stack) it gives the control to the first one interrupted.

5. The stack memory is addressed by a combination of the segment plus_ offset. 6. The PUSH and POP instructions always transfer -bit number between the stack and a register or memory location in the 8086 microprocessors. 7. For string instructions, DI always addresses data in the segment. 8. The 8086 LOOP instruction decrements register and tests it for a 0 to decide if a jump occurs 9. The last executable instruction in a procedure must be 10.A bus cycle is equal to clocking. periods. 11.

Code a descriptor that describes a memory segment that begins at location AB208000H and ends at location AC20AFFFH. The memory segment is a data segment that grows upward and can be written. The instruction used is a 32-bit size. it is assumed that the privilege level of the segment was set at 2nd highest and that the segment has not been accessed. NEED ASAP!!!
Whenever the CPU receives a signal, it stops whatever it is doing to deal with the incoming request. So, here's how the mechanism operates: Spooling with B as the interrupt signal C as the interrupt handler D as the polling method A'.
