The following 32-bit hexadecimal number describes a RISC-V machine instruction. Decode this instruction into a RISC-V assembly language statement (like `add x0, x1, x2`). To receive partial credit, you should show your steps including converting to binary format and identifying opcode, funct3, rs1, etc. 0x00C1F963

We would like to create an Assembly program whose executable is called division.exe and that behaves as follows:  It requests a positive number from the user.  Once it gets the user input, it divides the number by 5 without using the DIV instruction in assembly  It outputs the Quotient and the Remainder As an example, if a user runs the assembly program division.exe and provides a value 34 as an input, the display should show the following:...

Should be written in Python: A disassembler takes a machine code file (binary) and converts it back into assembly code. Disassemblers are a key tool in the software reverse engineering process because it allows you to go from the raw binary all the way back to the original source code, if desired. For this assignment you will be given 8 32-bit binary strings and the type of the instruction (I-type, R-type, or J-type). You’ll write a basic disassembler in Python...

MARIE Assembly Code Problem For the following problem, please create new MARIE instructions by providing the full MARIE RTN (register transfer notation) for the described operation. Your answer should include the fetch, decode, operand fetch (if necessary), execution and store result (if necessary) stages. When you see X in these instructions, this is a main memory address (the last 12 bits of the 16-bit instruction) – refer to this as IR[11..0] and not X. Problem: LoadZero X – this is...

Suppose we have an oracle (as in Turing Machine terminology, not the company) which can 4. tell us the factors of any composite number. Given our discussion on RSA, what advantage would such an oracle give to the code breaker? Explain how it would be used to compromise the RSA based public key authentication used in ssh.
