What is fetch execution?
Fetch execution refers to the process in computer architecture where the instruction fetch stage retrieves an instruction from memory to be executed by the CPU. This is typically the first step in the instruction cycle, where the program counter identifies the memory address of the next instruction to be fetched. Once fetched, the instruction is decoded and then executed, enabling the CPU to perform tasks as dictated by the program. Efficient fetch execution is crucial for overall system performance, as it impacts how quickly instructions can be processed.
How can you use estimation to place the decimal point in the quotient 42.56 divided by 22?
44/22 = 2 so the decimal point should be placed after the first digit (which is a 1).
Lizzy is tiling a kitchen floor for the first time. She had a tough time at first and placed only 6 tiles the first day. She started to go faster and by the end of day 4 she had placed 36 tiles. She w?
Lizzy's tiling progress can be modeled by a linear equation in slope-intercept form, y = mx + b, where y represents the number of tiles placed and x represents the number of days. By using the points (1, 6) and (4, 36), we can calculate the slope (m) as (36-6)/(4-1) = 30/3 = 10. Substituting one of the points into the equation, we can solve for the y-intercept (b) as 6 = 10(1) + b, giving b = -4. Therefore, the equation representing Lizzy's progress is y = 10x - 4.
What is difference between multi tasking and multiprogramming?
MultiTasking:In MultiTasking operating system, several jobs are executed in parallel by the operating system, through multiple processors (or) CPUs only.Like .CPU1: Job-ACPU2: Job-BCPU3: Job-CMultiprogramming :The method of Multiprogramming systems comes in the 1960s. In that process several different programs in batch were loaded in the computer memory, and the first one began to run. One program after another executed when the first program reached an instruction waiting for a device that has a message, the context of this program was stored away, and the second program in memory was given a chance to run. The process continued until all programs finished running.By : er.karthikchawda@gmail.com
What does it mean when less than and greater than are placed between two expressions?
This is used in computer languages (including spreadsheets like Excel) to indicate inequality. If two numbers are not equal, then the first one is either larger or smaller than the second one. This symbol is sometimes used because the standard inequality symbol is not readily available.
The first instruction in the ROM BIOS startup program is always assigned to?
Memory address FFFF0h is the memory address always assigned to the first instruction in the ROM BIOS
When a program begins the memory address of the first instruction is placed in a part of the microprocessors control unit called a(n) .?
When a program begins, the memory address of the first instruction is placed in a part of the microprocessor's control unit called the program counter (PC). The program counter keeps track of the address of the next instruction to be executed, ensuring the CPU can fetch and process instructions in the correct sequence. As each instruction is executed, the program counter is updated to point to the subsequent instruction in memory.
What memory is always assigned to the first intruction in the ROM BIOS?
The memory address FFFF0h is always assigned to the first instruction in the ROM BIOS startup program.
The virtual memory addressing capability of 80386 is?
NONE! The 80186 was an advanced version of the 8086 but did not include support for virtual memory. It had a 64K physical address space. The 80286 was the first Intel CPU to support virtual memory but it's capabilities were limited.
What are the examples of indirect addressing mode?
MOV AX,[2015H] meaning: first it refers to memory add 2015 n main memory the main memory in turns contains the address of operand, which is then fetched.
What is a cycle graph?
A cycle is a closed path such that the end vertex of the final edge is the start vertex of the first edge.
How many no of address lines required in 64kB memory?
To calculate the number of address lines required for a 64 kB memory, first convert 64 kB into bytes: 64 kB = 64 × 1024 bytes = 65,536 bytes. The number of address lines needed can be determined using the formula (2^n = \text{total number of addresses}), where (n) is the number of address lines. Since 65,536 is (2^{16}), you need 16 address lines to address a 64 kB memory.
How do you draw timing diagram of ADD M instruction?
I'm assuming that you mean "Add the contents of memory to an accumulator and place the sum back in the accumulator". First, the address of the memory location needs to be placed on the address bus and the control lines to memory need to be driven in such a way as to tell the memory that a write operation has been requested (usually enabling OE and synchronizing with a clock). Next (one or more clock cycles later depending on the type of memory being used), the data is returned from the memory. It must then be routed to the ALU. The value in the accumulator must also be moved to the ALU and can be performed in either the first or second CPU cycle, depending on the internal architecture of the CPU. It is probably safest to do this in the first cycle. Next the ALU must perform the addition instruction (third CPU cycle). Finally, in the fourth cycle, the result can be moved from the ALU back to the accumulator.
Where is the Memory Lane Museum Of Greater Yakima in Yakima Washington located?
The address of the Memory Lane Museum Of Greater Yakima is: 1511 South First St, Yakima, WA 98901-3543
What is the first test Test 0 performed by memtest86?
Test 0 [Address test, walking ones, no cache]Tests all address bits in all memory banks by using a walking ones address pattern.
Does a vertex delivery mean a vaginal delivery?
The word "vertex" tells you which part of the baby's head came out first. It implies a vaginal delivery.
How are elements of an array stored in memory?
Computer memory is linear so a one dimensional array can be mapped on to the memory cells in rather straight forward manner.To find the actual address of an element one needs to subtract one from the position of the desired entry and then add the result to the address of the the first cell in the sequence.Having said that therefore it is necessary to know the starting address of the space allocated to the array and the size of the each element, which is same for all the elements of an array.The the location of the Ith element would be B+I*S where B is the base address(Starting address of the array) and S is the size of each element of the array.
