Quad-C is a custom-designed multicore embedded system that integrates four ATmega328P microcontrollers onto a single PCB. Unlike traditional Arduino boards that rely on a single core for multitasking, Quad-C achieves true parallelism by distributing tasks across independent processors. Each microcontroller can be assigned dedicated roles—such as sensor data acquisition, motor control, or wireless communication—ensuring better responsiveness and modular design.

The board is powered by a custom task allocation library that enables seamless inter-core communication and coordination. This software layer abstracts low-level messaging, making it easy to assign and manage tasks across cores.

Programming:

Programming of the MCUs works through simultaneous application of equivalent code or unique code selection for specific tasks. The custom task allocation framework provides core coordination by which the system achieves effective multitasking capabilities while using modular software approaches.

Software:

The Quad-C board relies on an exclusive custom task allocation library as its main system component. The customized task allocation library enables microcontrollers to distribute tasks dynamically among each other which optimizes the processing resource utilization. Through the system developers have the ability to distribute individual tasks across MCUs which leads to both parallel processing and enhanced performance when handling real-time applications.
