A disk has a capacity of two tera-byte size. Say the file system uses a multi-level inode structure for locating the data blocks of afile.The inode stores pointers to data blocks, including a single indirect block, a double indirect block, and several direct blocks in the 64 B of available space.Now, it is given that the disk has a block size of 512 B. The maximum file size that can be stored in such a file system in MB (round off upto 2 decimal places).
Design a memory map to work with 8085 Microprocessor to have 8K byte ROM and 2K byte RAM. ROM should start from memory location 0000H and RAM immediately follows it. Use exhaustive decoding scheme?
A computer with a 32-bit word uses an instruction format that includes direct and indirect addressing of 8 megabytes and one of 16 registers. The highest order bits are used for the opcode, followed by the bits indicating the register, followed by the indirect/direct bit, followed by the bits indicating the memory address. Draw the instruction word's format, showing how many bits are used for all four fields (Make sure to show here how many bits for each and the order in which they appear. You can submit a drawing of the word's format separately
Write a complete Assembly Language program for (80x60) microprocessor to: Find the largest and smallest number from an array present in the memeory locations 0401-040A and store the Largest number in 040B (Largest No) and 040C (Smallest No). Note :numbers in the array are [67h,32h,6Fh,57h,22h,16h,08h,49h,78h,1Dh]. Show the output after execution.
Consider a memory implemented for 8086 microprocessor Draw the memory block diagram. Determine the values for A0 , /BHE ,address lines(A1..A19) and data lines(D0.. D15) in order to access: A byte at odd address [01FF3H] A byte at even address [01FFCH] A word at even address [01FFEH] A word at odd address [01ABFH]
Consider the following image that represents part of the memory of a 16-bit address space that has an addressability of 2 bytes (like LC-3): A memory location can store an address. We call that memory location's contents a "pointer" since it's an address that "points" to another memory location. G.) Interpret the contents at address 0x0C0B as a pointer. (Enter hex like the following example: 0x2A3F) H.) What are the contents of the memory location that the pointer above is pointing to? (Enter hex like the following example: 0x2A3F) Another reference : LC-3 Opcodes in Hex ADD 0x1 JMP 0xC LDR 0x6

4. You are drawing an octahedron (6 vertices, 8 triangles) and are considering whether to use an indexed polygon representation or a triangle-based representation. Assuming coordinates for vertices are given as 4 floatin point values and the indexes for polygons are given as 2-byte unsigned short values, how many bytes will each storage option take? Which is smaller? Note: you do not need to give either representation-only determine the amount of storage the representation would require.
Given memory partitions of 100K, 600K, 400K, 500K, and 300K (inorder), howwould each of the First-fit, Best-fit, and Worst-fitalgorithms place processes of 117K, 412K, 325K, and 510K (inorder)?
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.
Convert the following Compact Memory Notation diagram into an Array Memory Notation diagram. Assume the addresses are 4-bit binary values and the data are 8-bit binary values. Hint: The solution to this question is simply the reformatted diagram in Array Notation.
The use of transistors in the construction of RAM and ROM leads me to believe that there is no need for cache memory.The term "temporary storage" may also be thought of as "random access memory" (RAM) that is momentarily vacant. Imagine a machine that only had one kind of memory—is it even possible?
