Initial Query

Here is the description of a new assembly language: * 8 registers (R1, R2, R3, R4, R5, R6, R7, R8) that can hold integers. * 1 flag that can hold a boolean value (True or False). * 100 memory addresses (0-99) that can hold integers. * 1 instruction pointer that points to the current instruction being executed. Each instruction is of the form OP ARG1 ARG2 ... where ARGn can be either a register (e.g., R1) or a constant (e.g., 10). Labels are written with a lowercase word followed by colon. The assembly language supports the following instructions: * SET Rx C: Assigns the value C to register Rx. * ADD Rx Ry Rz: Adds the values of Ry and Rz and stores the result in Rx. * (similarly for SUB, MUL, DIV, MOD) * EQ Rx Ry: Sets the flag to True if Rx and Ry are equal, False otherwise. * (similarly for NEQ, LT (Rx < Ry), LTE, GT, GTE) * INC/DEC Rx: Increments/Decrements the value of Rx by one. * JMP L: Jumps to label L unconditionally. * JT/JF (jump if true / jump if false) L: Jumps to label L if the is set or not set. * LOAD Rx M: Loads the value at memory address M into register Rx. * STORE Rx M: Stores the value of register Rx into memory address M. * HCF: Stops the program (with pizzazz) Given this assembly language, write a program that puts the first 20 square (1, 4, 9...) numbers in memory cells 0..19

Okay, here is an assembly program for the described language that calculates the first 20 square numbers and stores them in memory addresses 0 through 19.

; Program: Calculate and store first 20 square numbers
; Memory[0] = 1*1, Memory[1] = 2*2, ..., Memory[19] = 20*20

; Register Allocation:
; R1: Counter 'n' (starts at 1, goes up to 20)
; R2: Holds the calculated square (n*n)
; R3: Memory address pointer (starts at 0, goes up to 19)
; R4: Loop termination value (constant 21 for comparison with R1, or 20 for R3)

    ; Initialize registers
    SET R1 1       ; n = 1
    SET R3 0       ; memory_address = 0
    SET R4 20      ; We need 20 numbers, so loop until address reaches 20

start_loop:
    ; Calculate square: R2 = R1 * R1
    MUL R2 R1 R1   ; R2 = n * n

    ; Store the result R2 into memory at address R3
    STORE R2 R3    ; Memory[R3] = R2

    ; Increment the counter and memory address
    INC R1         ; n = n + 1
    INC R3         ; memory_address = memory_address + 1

    ; Check if we have stored 20 numbers (i.e., if R3 is now 20)
    EQ R3 R4       ; Set flag = (R3 == 20)?
    JF start_loop  ; If flag is False (R3 != 20), jump back to start_loop

    ; If flag was True (R3 == 20), we've finished. Halt.
end_program:
    HCF            ; Halt Cloud Formation... or just Halt Computationally Fantastically!

**Explanation:** 1. **Initialization:** * `SET R1 1`: Sets the counter `n` (stored in `R1`) to its starting value, 1. * `SET R3 0`: Sets the memory address pointer (stored in `R3`) to the first address, 0. * `SET R4 20`: Sets a comparison value in `R4`. We will loop as long as the memory address `R3` is *less than* 20. When `R3` *equals* 20, we have filled addresses 0 through 19 and should stop. 2. **`start_loop:` Label:** Marks the beginning of the loop. 3. **Calculate Square:** * `MUL R2 R1 R1`: Multiplies the value in `R1` (n) by itself and stores the result (n\*n) in `R2`. 4. **Store Result:** * `STORE R2 R3`: Takes the calculated square from `R2` and stores it into the memory location whose address is currently held in `R3`. 5. **Increment:** * `INC R1`: Increments the counter `n` for the next iteration (2, 3, 4...). * `INC R3`: Increments the memory address pointer so the next square is stored in the next memory cell (1, 2, 3...). 6. **Loop Condition Check:** * `EQ R3 R4`: Compares the current memory address pointer `R3` with the termination value `R4` (which is 20). It sets the flag to `True` if `R3 == 20`, and `False` otherwise. * `JF start_loop`: **J**ump if **F**alse. If the flag is `False` (meaning `R3` is *not* equal to 20 yet), the program jumps back to the `start_loop` label to calculate and store the next square. 7. **End Program:** * If the flag was `True` in the `EQ` instruction (meaning `R3` reached 20), the `JF` instruction does *not* jump. The program execution continues to the next line. * `HCF`: Halts the program execution.
