So confusing right now
I have an LC-3 file and I need to use C# to read this one
0045 0120 25f0 0a56 0745 0145
then I need to use C# to print out the initial state for LC-3
machine which should look like this and after executing this
instruction

1.) a.) Using the simplified instruction set shown for part b, write code for the following. Suppose memory locations 1400 to 1449 contain 16-bit words. Each word represents 2 ASCII characters. Write code to read in and write out these 100 characters. Left-side character from location 1400 should be first, right-side character from location 1400 should be second, and remaining characters follow in numeric order. Assume you have access to 4 registers: R1, R2, R3, R4. Each register holds one...

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...

The AVR provides a rich instruction set to support high-level languages. The AVR address- ing modes also simplify the access of complex data structures. The AVR has a version of the ADD instruction that includes the C flag as one of the source operands, which enables multiple- precision addition operation. The AVR also has a version of the SUB instruction that includes the C flag as one of source operands and hence is used to perform multiprecision subtraction operation. The...
