### Instruction Set for a Simple ProcessorThis instruction set is supported by a simple processor, which has a few new instructions added. Its format is structured as follows:#### Instruction Format| bits | 15:14 | 13:10 | 9 | 8:6 | 5:3 | 2:0 ||------|-------|--------|---|-----|-----|-----|| field | unused | opcode | w | src1 | src2 | dst |- **opcode**: Defines the operation to be performed by the processor.- **w**: Determines if the ALU output should be written back to the register file (1 = yes, 0 = no).- **src1**: Address of the first ALU operand in the register file.- **src2**: Address of the second ALU operand in the register file.- **dst**: Address in the register file where the output is written.#### Special Cases for BEQ, BLEZ, and JUMPFor the opcodes BEQ, BLEZ, and JUMP, the 6 least significant bits (5:0) provide an address in the instruction memory, which is byte-addressed. The opcode HALT has all operand bits (9:0) as zero. When an instruction has only two operands, the unused operand's field is filled with zeros. For example, in the case of SLL, bits (5:3) are zero since src2 is not used.#### Opcode and MeaningThe table below lists the opcode, binary encoding, and operations for these instructions:| Opcode | Binary Encoding | Operation ||--------|-----------------|----------------------------------------|| ADD | 0x0 | R[src1] + R[src2] → R[dst] || SUB | 0x1 | R[src1] - R[src2] → R[dst] || SLL | 0x2 | R[src1] << 1 → R[dst] || SRL | 0x3 | R[src1] >> 1 → R[dst] || INV | 0x4 | ~R[src1] → R[dst] || XOR | 0x5 | R[src1] ^ R[src2] → R[dst] || OR ### Machine Code Disassembly Exercise1. **Objective**: This exercise involves translating a segment of machine code into assembly code and annotating it with expressions in a high-level language like C. This process is called "disassembling," where you convert binary code back to source code. Your task is to disassemble the following machine code into operations and arguments (e.g., ADD R1, R2, R3) and explain the program's function in plain English or C-like pseudocode. Unique labels should be created for branch instructions in the assembly code.### Machine Code```Addr: Code--------------------0x00 07FE0x02 240E0x04 1E0C0x06 250A0x08 03F90x0A 0E000x0C 24C20x0E 3C00```- **Explanation Task**: - Convert the above machine code into assembly instructions. - Provide a high-level explanation or pseudocode of what the entire segment accomplishes (e.g., "it calculates the product of R1 and R2" or "R3 = R1 * R2"). > **Note**: Ensure to create unique labels for any branch instructions during the disassembly process.

Which of the following are true about the comparison between 2-pass and 1-pass compilers? Choose the most correct THREE answers. Question 8 options: C language implementations are generally meant to work with 1-pass compilers. Function prototypes may be necessary in the case of a 1-pass compilation. 1-pass compilers have to see the declarations of a variable or function before it can be used in the code. Executable files generated by 1-pass compilation will result in faster running programs than 2-pass compilation. C requires pointers because of 1-pass compilation.

Write the code in python programming for the below problem. Introduction One useful data point in detecting fraud is the account history of a customer. For an account, we receive notification of purchases and, sometimes, reports of fraud. Typically, a prior report of fraud for an account would increase the perceived risk of fraud on future transactions. Similarly, a history of non-fraudulent purchases for an account would decrease the risk of fraud. A credit card holder has 90 days to report any fraudulent transactions with the card. So if an account has purchases over 90 days old and no reports of fraud, we assume that these older purchases were not-fraudulent. Problem Description The purpose of this programming problem is to determine the status of a customer account history at the time a new purchase is made. The input is a sequence of customer account events, in chronological order. Each event has three fields, all of which are of string type ,, For example:…

You are expected to use python Object-Oriented programming concepts to design and implement a system in python for building a scientific calculator which inherits its basic operations from a standard calculator. The standard calculator can perform two types of operations: an addition and a subtraction The standard calculator is capable of inputting only two integers. But the scientific calculators can also interpret decimal values. The scientific calculator is capable of four operations: addition, subtraction, cosine and sine of values. The scientific calculator can accept multiple values for the addition operation. After performing an addition, the scientific calculator will send the final result to a database. (You are not expected to write the codes for the database connection and the queries. You are expected to only show how you can use your scientific calculator object to pass messages to a database object) Create 100 objects for your scientific calculator to enable…
Instruction: Answer question 4 (a,b & c) only (1) Create a C++ project for your assignment 3, with the name format prescribed in the Information section. Add a source file and name it SwapCount. In this file, write the C++ program that will perform the tasks specified in question 2.(2) Declare and implement a function called sortSwapCount that passes three parameters, the array, the size and the reference of proportion, and returns the count. The functiondeclaration is int sortSwapCount(int data[], int size, double& proportion) (i) The function sorts the integers in data[] in ascending order using the bubble sort method. The purpose is to count or determine the number of exchanges (swaps) made by the bubble sort algorithm. (ii) The expected number of sorting swaps (expectedSwapCount) is size * (size - 1) if the array was unsorted. Calculate the proportion of the array status by first converting (or casting) the integers, swapCount and expectedSwapCount into floating-point,…
