- A number of LC-3 instructions have an "evaluate address" step in the instruction cycle, in which a 16-bit address is constructed and written to the Memory Address Register via the MARMUX. List all LC-3 instructions that write to the MAR during the evaluate address phase of the instruction cycle, with the Register Transfer description of each.arrow_forwardFull explanation of what you did please step by steparrow_forwardPlease explain the instructions starting with R, J, and I that follow. I'm quite grateful for it. The several instruction set variations, their differences, and instruction set architecture are explained in this article (ISA). ?arrow_forward
- The microprocessor provides the inputs for the hardware interrupts in the form of a non-maskable interrupt (NMI) and an interrupt request. Both of these are considered to be types of interrupts (INTR). Do you think you can tell the difference between the two?arrow_forwardIt is more probable that programs developed for zero-address, one-address, or two-address architecture will be lengthier (have more instructions). Why?arrow_forwardWhat is instruction latency, and how is it affected by pipelining?arrow_forward
- i) Are assembly instruction different in terms of their efficiency? If yes why and if no, why not? Explain with the help of an example. ii) What is the purpose of Flags in assembly language. How does it make the architecture and code more efficient? Explain with the help of an example.arrow_forwardWrite an assembly code to assign the register BX with 4014H, and register DX with 4028 H. Move the content of BX to DX, und verse versa. Then, copy the now value of low content for BX and DX .to memory location [2131 H], and [2139H]arrow_forwardWhat are the pros and cons of using single address instructions?arrow_forward
- If you have an architecture which has base and bound registers where there is one base register and one bound register per program, is it possible to have two programs share data?arrow_forwardAssembler instructions may be rearranged to mitigate pipeline security risks. Is there a difference in the ways in which assemblers and compilers arrange instructions for assembly language?arrow_forwardThe inputs for hardware interrupts are provided by the microprocessor in the form of a non-maskable interrupt (NMI) and an interrupt request (INTR). Is it feasible for you to tell the difference between the two?arrow_forward
