What happens when an instruction Add 3000 is executed?
TRUE A branch or jump instruction can cause the processor to execute instructions out of memory-address order. FALSE The instruction ADD 3000, 2000, 3080 adds the values 2000 and 3080 together, and places the result (5080) into the memory location having address 3000.
What is locality of reference Mcq?
Explanation: The spatial aspect of locality of reference tells that the nearby instruction is more likely to be executed in future. Explanation: When write operation is issued then the corresponding operation is performed.
What is memory addressing techniques?
The addressing mode specifies a rule for interpreting or modifying the address field of the instruction before the operand is actually executed. The 8086 memory addressing modes provide flexible access to memory, allowing you to easily access variables, arrays, records, pointers, and other complex data types.
What is a zero address instruction?
It may for example enable stack processing: a zero-address instruction implies that the absolute address of the operand is held in a special register that is automatically incremented (or decremented) to point to the location of the top of the stack.
Which is an example of memory address in a computer?
Address Address Memory addressing Example – for a Computer – Word = 16 bits – Byte addressable – uses big-endian – Long word = 4 bytes – 24 bits used for address 16 M bytes or 8 M words Instructions and instruction sequencing 4 bits 12 bits Address Inf.
How many addresses do you need for 4m x 8 bit memory?
For #2 and #3, the answers provided in our lecture was: 4M X 8 bit memory requires 21 bit addresses if it is word-addressable and word size is 16 bits. 4M X 8 bit memory requires 20 bit addresses if it is word-addressable and word size is 32 bits.
How many bits do you need to address 2m words?
#2 and #3 of the lecture are a bit confusing. If the memory is word-addressable with 16-bit words, it’s no longer a 4Mx8 memory but a 2Mx16 memory. To address 2M words you need 21 bits. Similar for #3.
What kind of memory is needed for 2m words?
If the memory is word-addressable with 16-bit words, it’s no longer a 4Mx8 memory but a 2Mx16 memory. To address 2M words you need 21 bits. Similar for #3. Thanks for contributing an answer to Electrical Engineering Stack Exchange!
