METACONTROLADORES: UNA ALTERNATIVA PARA EL CONTROL DE DISPOSITIVOS EN UN RTOS (META-DRIVERS: A NOVEL APPROACH TO DEVICE CONTROL IN RTOS)
Resumen
En este trabajo se presenta una alternativa para el control de dispositivos en un sistema embebido, donde cada uno requiere un controlador independiente, sin embargo, el mejor aprovechamiento de los recursos limitados puede impactar considerablemente su desempeño. Mediante el uso de metacontroladores es posible reducir los requerimientos de memoria y tiempo de desarrollo, así como la posibilidad de soportar nuevos dispositivos. Para tal fin, se presenta una metodología que se basa en analizar las señales de control, permitiendo identificar patrones y crear un diccionario para soportar los periféricos. Las simulaciones comportamentales realizadas en EMOS, aceleraron el proceso de depuración para las palabras diseñadas, siendo éstas utilizadas 144 veces en el SSDS. Además, las mediciones experimentales con una tarjeta Raspberry Pi Pico validan la metodología propuesta. Finalmente, se determina que existe una correspondencia del 100% en las palabras utilizadas para los casos analizados, reduciendo la ocupación de memoria RAM del microcontrolador.

Abstract
This paper presents an alternative approach for device control in embedded systems, where each device generally requires an independent driver. However, efficient utilization of limited system resources can significantly enhance overall performance. The use of metadrivers enables a reduction in memory requirements and development time, while also facilitating the integration of new devices. To achieve this, a methodology is proposed based on the analysis of control signals, allowing for the identification of patterns and the construction of a dictionary to support peripheral devices. Behavioral simulations performed using EMOS accelerated the debugging process of the designed control words, which were utilized 144 times in the SSDS. In addition, experimental measurements conducted on a Raspberry Pi Pico board validate the proposed methodology. Results show a 100% match of the control words for the analyzed cases, along with a reduction in RAM usage on the microcontroller.
Keywords: Metadriver, metalanguage, real-time, RTOS.
