Instead of inserting NOPS you let the process stall on hazards. How many times does the processor stall? How long is each stall (in cycles)? What is the execution time (in cycles) for the entire program? Assume that full-forwarding has been added. write the program with NOPs to eliminate the hazards. Note: Delay slots are not used.

AIM- Write an 8085 sequence to check whether the first set of reading is higher than the second one or not. PROBLEM STATEMENT- The pressure of two boilers is monitored and controlled by a microcomputer works based on microprocessor programming. A set of 6 readings of first boiler, recorded by six pressure sensors, which are stored in the memory location starting from 2050H. A corresponding set of 6 reading from the second boiler is stored at the memory location starting from 2060H. Each reading from the first set is expected to be higher than the corresponding position in the second set of readings. Write an 8085 sequence to check whether the first set of reading is higher than the second one or not. If all the readings of first set is higher than the second set, store 00 in the 'D' register. If any one of the readings is lower than the corresponding reading of second set, stop the process and store FF in the register 'D'. Data (H): First set: 78, 89, 6A, 80, 90, 85 Second Set:71, 78,…

1.1 Please follow the instructions below The goal of this problem is to use iteration (nested for loops) and condition statements ( statements) to create a pattern for any digit between 0 and 9. In particular, your task is to write a program in C programming language to prompt the user to input a digit and also the width and height of that digit The program will finally output the pattern of the digit with the chosen height and width (the input needs to be vaided as shown in the sample run). As an example the following gidsdsplay the sample pattom for each digt with chosen height-7 and width H 8 Your program should accept only a single digit (at a time) and any odd value within the range [515] for both the width and height (of the digit). You need to da enor checking to be sure the width and height both are add value and also within the mentioned range (>5 and 15). Try to design the code to be as simple as possible and you can use the asterisk (") and the space character to print the…
Instruction: Rank the given pseudocode (see the attached photo) according to its order of action. In the program flow, the input and checking sequence should be in the following order: number of people checked in, stay duration, meal charges. Furthermore, checking for the number of people should be in increasing order. Pls be guided in the given problem. Problem: Problem: Write a pseudocode to compute for the bill: An inn charges for room use (per night) at PhP 500 per one person, PhP 750 for two people, and PhP 1500 for at least three people. Meal charges, separately computed and to be prepared by the hotel management, will be added to the total bill.
I need help please to write a program in Assembly programming language for a grocery store to calculate the total charge for customers following thisalgorithm: 1. In the main:a) ask customer for the number of items that they are purchasingb) check to see it is less than or equal to 20 itemsc) pass than number to FillPriceArray subroutine and call FillPriceArray subroutine.2. FillPriceArray subroutine:a) fill the array and accumulate the prices sub totalb) return the sub total to main.3. In the main:a) ask customer for the number of coupons (it should be the same as the number ofitems)b) pass the coupon number to FillCouponArray subroutine and call FillCouponArraysubroutine to fill the CouponArray.4. FillCouponArray subroutine:a) fills the array and accumulate the discount total*get the coupon amount:The coupon should be less than item price and coupon should not be more than $10if the coupon is more than item price or exceed $10 then you place 0 in theCouponArray for that coupon.b)…
Overall Requirements Write two programs encode.toy and decode.toy. Each TOY instruction must have corresponding pseudocode. (This is auto-generated by Visual X-Toy – see below.) It's also good practice to add line breaks between logically related "sections" of TOY code and write a comment above each "section" explaining what that code does. encode.toy Write a TOY program encode.toy to encode a binary message using the scheme described above. Repeatedly read four (4) bits m1, m2, m3, m4 from TOY standard input and write the seven (7) bits m1, m2, m3, m4, p1, p2, p3 to TOY standard output. Stop upon reading FFFF from standard input. p1 = m1 ^ m2 ^ m4 p2 = m1 ^ m3 ^ m4 p3 = m2 ^ m3 ^ m4 Recall that ^ is the exclusive or operator in Java and TOY. This captures the parity concept described above. decode.toy Write a TOY program decode.toy to decode and correct a Hamming encoded message. Repeatedly read seven (7) bits m1, m2, m3, m4, p1, p2, p3 from TOY standard input and write the four…
