Brief Explanation of Functional SCALA:

Functional Scala emphasizes immutability and the use of functions as first-class objects. The main focus is on declarative programming, where you describe what your program should do, rather than how to do it, relying heavily on recursion and higher-order functions. Here's a quick breakdown:

• Immutability: Variables, once initialized, cannot be altered, preventing unintended side effects.
• Pure Functions: Functions that return the same output given the same input and have no side effects.
• Higher-Order Functions: Functions that take other functions as parameters or return them.
• Pattern Matching: A powerful feature that simplifies control flow by matching data structures directly.

LOGISIM -> Single Cycle Processor

Branch: Circuits

1. Program Counter: Tracks the current instruction address and increments by 4 (or jumps for branch/jump instructions).
2. Instruction Memory: Stores the set of instructions that the processor executes in binary form.
3. Control Decoder: Reads the opcode from the instruction and generates the necessary control signals (ALUOp, MemRead, MemWrite, etc.).
4. Register File: Stores temporary data in registers (x0 through x31). The write-back stage writes results back here.
5. ALU: Performs all arithmetic and logical operations, such as addition, subtraction, AND, OR, and compares.
6. Data Memory: Contains memory for data that is read from or written to, based on the instruction (e.g., lw, sw).
7. Data Memory Interface: Ensures correct communication between the ALU and memory for loading/storing operations.
8. Write Back: Handles writing the results of computations back to the register file.

Software Setup:

• Software: logisim-win-2.7.1
• Extensions:
  • jre-8u421-windows-x64

File Format:

• Logisim files use the .circuits extension.
