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.
Code a descriptor that describes a data memory segment that grows upward and begins at location 03000000H and ends at location 05FFFFFFH and can be written. The memory has not been accessed, and can be accessed with the lowest privilege level. Assume that the segment is available (i.e., AV=1) and that the instructions are 32 bits (i.e., D=1).
Code a descriptor that describes a memory segment that begins at location 0005CF00h and ends at location 00060EFFh. The memory segment is a data segment that grows upward in the memory system and can be written. The segment has a user level privilege (lowest) and has not been accessed. The descriptor is for an 80386 microprocessor.

the oneratinn 3) Suppose an application program requires 2500H bytes of memory for its code, 2FOH bytes of memory for its data, and 2A0H bytes of memory for its stack. Shows how this application is positioned in a memory with a 20-bit address bus if locations 00000OH to 0A000H is reserved for the operating system (OS) softtware.
The control signal Ep or iEnableoutput allows the program counter to decrement its value. True False The control signal Ep or iEnableoutput sends the content of the program counter to the W bus. True False A tri-state buffer is needed for all data going to the W bus. True False In using 'assign' statement in Verilog, the left hand side must always be a register. True False In declaring a register in Verilog, the following format must be followed: reg [LSB:MSB] identifier; True False
Read-only memory (usually known by its acronym, ROM) is a class of storage media used in computers and other electronic devices that is non-volatile (non-changeable). Because data stored in ROM cannot be modified (at least not very quickly or easily), it is mainly used to distribute firmware (software that is very closely tied to specific hardware, and unlikely to require frequent updates). Figure 3.1 depicts a ROM block diagram which have k-bit address and an n-bit data. The contents of a ROM chip are defined once. Hence, we can use a constant array to model a ROM in VHDL. Basically, to name the size of a ROM is by stating ROM k x n, which represents ROM with k-bit address andn-bit data size. For example, ROM 4x8 (16 address location with each location containing 8-bit data). Question. Develop a code to allow the ROM operation works in synchronous when a read enable is asserted.• Generate and simulate the VHDL codes in Altera Quartus II.• Demonstrate and obtain the instructor…
In the S/370 architecture, a storage key is a control field associated with each page- sized frame of real memory. Two bits of that key that are relevant for page replace- ment are the reference bit and the change bit. The reference bit is set to 1 when any address within the frame is accessed for read or write, and is set to 0 when a new page is loaded into the frame. The change bit is set to 1 when a write operation is per- formed on any location within the frame. Suggest an approach for determining which page frames are least-recently-used, making use of only the reference bit.
In a main memory-disk virtual storage system, the page size is 1KByte and the FIFO algorithm is used for page replacements. A given program has been allocated three page frames in the main memory and it makes the following 16 memory references when it starts executing (the addresses are given in decimal):500, 2000, 2500, 800, 4000, 1000, 5500, 1500, 2800, 400, 5000, 700, 2100, 3500, 900, 2400 Fill in the contents of the three page frames after each memory reference in a table and calculate the hit ratio. Hint: denote by 'a' the page consisting of locations 0 through 1023 in memory. Similarly, b: 1024-2047, c: 2048-3071, d: 3072-4095, e: 4096-5119 and f: 5120-6143. Round to three decimal places.
Paging: Select all of the following statements that are true. Systems that use paging but do not support inverted page tables maintain at least one separate page table for each process. The frame table is a system-wide data structure. When paging is applied, the selected page size determines which part of a virtual address belongs to the page number and which to the offset. The page size may differ from the frame size. The Translation Look-aside Buffer (TLB) represents a page directory for all pages in the system. Paging is prone to internal fragmentation.
