Write the mnemonics of the following program:
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, 65, 89, 56, 75

The screen has width w, where w is divisible by 8 (that is, no byte willbe split across rows). The height of the screen, of course, can be derived from the length of the arrayand the width. Implement a function that draws a horizontal line from ( xl, y) to ( x2, y).The method signature should look something like:drawline(byte[] screen, int width, int xl, int x2, int y)arrow_forward

- An online computer system for trading stocks needs to process orders of the form "buy 100 shares at $x each" or "sell 100 shares at $y each." A buy order for $x can only be processed if there is an existing sell order with price $y such that y≤x . Likewise, a sell order for $y can only be processed if there is an existing buy order with price $x such that y≤x . If a buy or sell order is entered but cannot be processed, it must wait for a future order that allows it to be processed. Write a program that can process a sequence of stock buy and sell orders as described above. Use the Python heapq module. Follow this scheme to buy/sell the order in O(log n) time: According to the given scenario on trading the stocks to buy or sell 100 shares, the following is the best scheme: • Initially, let us create the two heap structures. One heap to buy the orders and other heap structure to sell the orders. • Next store the quantity and price in each node with the price as key. • If the order is…arrow_forwardPART 1: Find the Nth Fibonacci Number (Objective - 4)You will implement a function for finding the nth Fibonacci number using the MIPS assembly language.
