About

riser16 is a 16-bit computer project that visualizes the low-level workings of computers. This project follows a Von Neumann architecture, using a common bus for both data and addressing. The complete description of its architecture and specifications are as follows:

Hardware Specifications:

• Architecture: Von Neumann with a common data and address bus.
• Word Size: 16-bit.
• ALU (Arithmetic Logic Unit): 8 modes.
• Flag Registers: 2 flags - Carry and Zero.
• General Purpose Registers: 2 registers - X and Y.
• RAM Size: 64KB (2^16).
• Microinstruction Cycle: Maximum 16 cycles for NOP (No Operation) and minimum 3 cycles for SKIP.
• Display: Two types - Hex display and 256x128 pixel display.
• Instruction Set Capacity: Complex instruction set with 256 (2^8) possible instructions.
• Turing Complete: Yes.

Features:

• Von Neumann Architecture: This architecture allows both data and instructions to be stored in the same memory space, simplifying the design and operation of the computer.
• 16-bit Word Size: Enables the processing of larger amounts of data in a single operation compared to smaller word sizes.
• ALU: The 8-mode ALU provides flexibility in performing various arithmetic and logic operations.
• Flag Registers: Carry and Zero flags are essential for arithmetic operations and branching decisions.
• General Purpose Registers: X and Y registers offer data storage for operations.
• Large Memory: 64KB RAM provides ample space for programs and data.
• Efficient Microinstruction Cycle: Optimized for both simple and complex operations, balancing speed and functionality.
• Dual Display: The Hex display and pixel display enhance the visualization of data and operations.
• Complex Instruction Set: Supports a wide range of operations, making it suitable for complex computational tasks.
• Turing Completeness: Capable of performing any computation given enough time and resources, demonstrating its power and flexibility.
