MiniMac
MiniMac is a virtual processor with a tiny but extendable memory and a tiny but extendable instruction set.
Here’s a screenshot of the MiniMac user interface:
The view panel on the right contains two lists (javax.swing.JList). The top list shows the contents of memory. The bottom list shows the program currently being executed. The control panel on the left contains three buttons (javax.swing.JButton). The first button prompts the user for a program to parse:
The second button executes the program. The third button resets all memory cells to 0.
These commands are duplicated under the Edit menu. The Help menu explains each command. The File menu contains the items: New, Save, Open, and Quit.
The MiniMax memory is an array of integers:
int size = 32;
Integer[] memory = new Integer[size];
A MiniMax program is a list of instructions. An instruction pointer (ip) indicates the position in the list of the next instruction to be executed.
Grammar
Here’s the instruction set grammar (note: “~” means “followed by” and all unquoted tokens are integers):
Load ::= “load” ~ location ~ value // memory[location] = value
Halt ::= “halt” // terminates the program
add ::= “add” ~ src1 ~ src2 ~ dest // memory[dest] = memory[src1] + memory[src2]
mul ::= “mul” ~ src1 ~ src2 ~ dest // memory[dest] = memory[src1] * memory[src2]
bgt ::= “bgt” ~ location ~ offset // if 0 < memory[location] ip += offset blt ::= “blt” ~ location ~ offset // if memory[location] < 0 ip += offset loop ::= “loop ~ count ~ instruction // executes instruction count times A block is a list of one or more instructions separated by semicolons and bracketed by curly braces: block ::= “{“ ~ instruction ~ (“;” ~ instruction)* ~ “}” Executing a block sequentially executes each instruction in the block’s body. For example, the program shown in the screenshot computes kn, where n is stored in memory[0]. The base, k, is stored in memory[2]. In this case k = 2, n was 7 and the result, 128, is stored in memory[1]. Memory[3] is the amount to decrement memory[0] each time the result is multiplied by k. Design Here’s the design of MiniMac: Parser Here’s a partial implementation of MiniMacParser.java. Note that it is a utility class (aka singleton), all of its methods are static. Testing Implement and test the following functions in MiniMax: Tri(n) = 1 + 2 + ... + n // stored in a file called tri Fib(n) = nth Fibonacci number // stored in a file called fib Less(n, m) = (n < m)?1:0 // 1 = true and 0 = false Log(n) = m where 2m <= n and n < 2m+1 In each case the input, n, should be stored in memory[0] and the output, f(n), should be stored in memory[1]. Hints 1.The MiniMax is a publisher and the view panel is its subscriber. Each time memory is updated or a new program is set, MiniMax notifies its subscribers. 2.The control panel is the action listener for its buttons. It navigates to the MiniMax and calls the appropriate procedure (execute and clear). 3.Parsing is more complicated. The control panel must prompt the user for a file name, read the file (as a string), then pass the string to MiniMaxParser.parse(program). It then sets the MiniMax program to the parser’s output, which causes a subscriber notification. Suggestion: ask ChatGPT how to read a text file in Java. 4.Ask ChatGPT for a simple example of how to use a JList.
