I have a coding assignment that requires me to create a program in C#, within Visual Studio, that simulates MARIE. It needs to have global variables such as PC, MAR, MBR, AC, IR, etc. It needs to implement, fetch, decode and execute cycles. For instance, during the fetch cycle, the code needs to first place PC in MAR, then use MAR to access memory (array element) and grab the content and put it in IR and increment PC.

For example, let's say PC = 0, the code will place PC which is zero inside MAR, now MAR is zero, then the program will read memory[MAR] and save its content in IR register (variable) and increment PC which becomes 1. Next, you will check the first 4 bits of IR (in this example it is 0001, based on the 4 bits, the program needs to call Load function. Since Load command has an operant, the code also needs to put the remaining 12 bits of the IR inside MAR to be able to access the memory location MAR. Next, it grabs the content of memory[MAR] and converts it into integer (decimal value) and loads it into AC.

Some of these variables must be of type string, for instance the IR register and some of them such as PC is of type int. It also needs to implement functions to convert binary to decimal and a function to convert decimal to binary.

Here are some of the arrays that need to go into visual studio but I don't know what else needs to go with it:

memory[0] = "0001000000010001"; // Load Addr

memory[1] = "0010000000010010"; // Store Next

memory[2] = "0001000000010011"; // Load Num

memory[3] = "0100000000010110"; //Subt One

memory[4] = "0010000000010101"; // Store Ctr

memory[5] = "0001000000010100"; //LOOP: Load Sum

memory[6] = "1011000000010010"; // AddI Next

memory[7] = "0010000000010100"; //Store Sum

memory[8] = "0001000000010010"; //Load Next

memory[9] = "0011000000010110"; //Add One

memory[10] = "0010000000010010"; //Store Next

memory[11] = "0001000000010101"; // Load Ctr

memory[12] = "0100000000010110"; //Subt One

memory[13] = "0010000000010101"; //Store Ctr

memory[14] = "1000000000000000"; // Skipcond

memory[15] = "1001000000000101"; //Jump

memory[16] = "0111000000000000"; // Halt

memory[17] = "0000000000010111"; //Addr

memory[18] = "0000000000000000"; // Next

memory[19] = "0000000000000101"; // Num

memory[20] = "0000000000000000"; //Sum

memory[21] = "0000000000000000"; // Ctr

memory[22] = "0000000000000001"; //One

memory[23] = "0000000000001010"; //Dec 10

memory[24] = "0000000000001111"; // Dec 15

memory[25] = "0000000000010100"; //Dec 20

memory[26] = "0000000000011001"; //Dec 25

memory[27] = "0000000000011110"; //Dec 30

What I have tried:

I've tried seeing if YouTube has any tutorials and so I don't know where to start and I've never coded anything like this before.
