- If a microprocessor has a cycle time of 0.5 nanoseconds, what’s the processor clock rate? If the fetch cycle is 40% of the processor cycle time, what memory access speed is required to implement load operations with zero wait states and load operations with two wait states?A(n) ________________ instruction always alters the instruction execution sequence. A(n) ______________ instruction alters the instruction execution sequence only if a specified Condition is true.Superscalar processor could be a central processor that implements instruction-level correspondence inside one processor. It will execute over one instruction throughout a clock cycle. It at the same time dispatches multiple directions to completely different execution units on the processor. False True
- Under the von Neumann architecture, a program and its dataare both stored in memory. It is therefore possible for a program,thinking that a memory location holds a piece of data when itactually holds a program instruction, to accidentally (or onpurpose) modify itself. What implications does this present to youas a programmer?Read the given scenario and answer questions based on 8086 microprocessor architecture. A programmer has written Assembly Language Program (ALP) using 8086 instruction set. The program will read any 200 user given inputs and process them to generate 200 outputs using stack. Each input and output is a byte length data. The input values are read from memory location D217H onward and the output values are stored from memory location E106H onward. The program uses a stack and the stack is defined from the memory location 54DAH and it can store 500 values. The program has 450 instructions stored from the memory location 6E20H to 713DH. The last instruction is HLT which is a byte long instruction. Identify the segments of the given memory locations Memory Location 6EEEH Code Segment Memory Location D2D0, Data Segment Memory Location 55A2H Stack Segment What will be the value of the Instruction Pointer (IP) when the program is about to execute the 449th instruction which is of a two address…Write a program in MARIE assembly language to perform following code segment. Test your code thoroughly using MARIE simulator with values of X=1, X=9, and X=10. What is the value stored in X by the end of execution? Include comments for each line of instruction in your program. X = 1while X < 10 do;X = X + 1endwhile;
- An interrupt from a CPU causes the processor to halt what it is doing and react to the signal. What is the reason for pausing the operation in order to accomplish the task? Let's start with the process of interrupting, and then go on to the process of executing. explain?The architecture of a CPU may consist of a universal register, a singular accumulator, or a stack. Each has benefits and drawbacks. Your response could be correct or incorrect.Consider a door locking system which has an LCD connected to it to show the status of door (for example locked and unlocked). Design an assembly language code such that when user press 1 door is locked and when user press 2 the door is unlocked. Display the corresponding status on first line of LCD and registration no on second line of LCD. write a code in microprocessor assembly language
- An interrupt from a CPU causes the processor to cease what it is doing and react to the signal received by the processor. What is the reason for pausing the operation in order to finish this task? Let's start with the process of interrupting and then go on to the process of executing. explain?When a computer processor has many instructions running at once, how can it prevent wasting computation cycles that it would otherwise utilise if it were only carrying out one instruction? It should be indicated what occurred as a direct result of what they did in the previous phrase.Consider a system in which Data and Code are distinct. When necessary, the CPU acquires instructions or data using two base-limit register pairs. Data and instructions should be kept separate. By default, this pair is read-only, allowing several users to share the programme. This method should be compared to others.
