حرکت شتابدار به سوی دنیای Embedded System و نقش نرم‌افزارهای آزاد بر آن

227 views

Published on

استفاده از مفهوم نرم‌افزار آزاد، پیشرفت‌های شگرفی را در حوزه‌های مرتبط با علوم کامپیوتری در دو دههٔ اخیر به همراه داشته است. بهبود عملکرد و پیشرفت در قابلیت اطمینان و صحت کارکرد، از مهم‌ترین دستاوردهای ورود مفاهیم نرم‌افزارهای آزاد و متن‌باز به حوزه علوم کامپیوتری بود. در چندین سال اخیر، این مفاهیم به حوزهٔ الکترونیک و سخت‌افزار نیز وارد شده و با ورود خود موجب افزایش قابلیت اطمینان، بهبود در راندمان، کاهش زمان طراحی (از ایده تا اجرا) و افزایش سرعت تولید محصولات الکترونیکی و مکاترونیکی شده است. در واقع تاریخ در این حوزه نیز تکرار شده است. در این میان، نقش سیستم‌های عامل متن‌باز همانند گنو/لینوکس، که دقیقاً به علت آزاد و متن‌باز بودن به راحتی به معماری‌های مختلف سخت‌افزاری پورت شده‌اند، بسیار پررنگ و حائز اهمیت است. در سال‌های اخیر، گنو/لینوکس و مشتقات آن، با قدرتی بی‌نظیر، به شکلی متفاوت و بسیار ساده به حوزه سخت‌افزار وارد شده است. انتظار می‌رود با ورود شرکت‌های بزرگ سخت‌افزاری دنیا همانند اینتل، سامسونگ و بسیاری از شرکت‌های مهم دیگر در سال‌های پیش رو، حوزه‌های الکترونیک، اینترنت اشیا (IoT)، نرم‌افزارهای آزاد و جامعه آن‌ها، سیستم‌های بر روی تراشه (SoC) و کامپیوترهای فوق کوچک دارای سیستم‌عامل، با یکدیگر ترکیب و بیش از پیش موجب تحول در کسب و کارهای سنتی و مبتنی بر روش‌های قدیمی طراحی سخت‌افزار شود. در این مقاله نگاهی به پیشرفت‌های حاصل شده در این زمینه و انتظارات سالهای پیش رو خواهیم داشت.
