Write a C program which will display the contents of a file in base-16 (hexadecimal) and in ASCII. Complete the following tasks: Obtain the name of the input file from the command line. If the command-line is “./hexdump xxx.bin” then argv[1] will contain “xxx.bin”. Open the file for binary input Print the entire file, 16-bytes per line. Each line should begin with an 8-digit hexadecimal offset into the file. This is the count of the bytes that you have already...

Implement the following statements using MS430 assembly instructions. You may use more than one, but you should minimize the number of instructions required. You can use both native and emulated instructions. Use hex notation for all numbers 1. (a) Move the word located in register R14 to R15 (b) Increment the word in R6 by 2. (c) Perform a bitwise ANDing of the word located at address 0x0240 with the datum in R15, placing the results in R15. (d) Rotate...
