BCPU-MCPU-HCPU

Explanations about the 3 processors and releases

BCPU (Basic Central Processing Unit):

• The BCPU is the simplest processor in this line, designed primarily for educational purposes, testing, and as a foundational example of processor architecture. It typically has a 4-bit architecture and a low clock frequency. The objective of the BCPU is to demonstrate basic processing concepts and execute simple operations, such as the Fibonacci sequence.
• Only the BCPU has fixed instructions, which are predefined by the opcode itself, rather than being dynamically selected through buses. Instead of general-purpose instructions like MOV [ADDR] TO [ADDR], the BCPU uses predefined instructions such as MOV R1 TO R2, each represented by a specific opcode.

MCPU (Medium Central Processing Unit):

• The MCPU is designed to be a more focused processor compared to the BCPU. With its 8-bit architecture and reasonable clock frequency, the MCPU is capable of handling user input and interacting with graphical output. Its objective is to allow more dynamic and interactive operations.
• Unlike the BCPU, the MCPU introduces dynamic instruction handling, where a single opcode can represent multiple instructions by using buses to select which operation to execute. This allows for much more flexibility in programming and handling complex tasks.

HCPU (High Central Processing Unit):

• The HCPU is the most powerful processor in this line, featuring a 16-bit architecture and a high clock frequency. It is designed to handle complex applications and can be capable of executing simple games such as Snake, Tic Tac Toe, and Pong.
• The HCPU uses the same dynamic instruction technology as the MCPU, allowing complex operations and flexibility through the use of buses also.
