Embedded Operating Systems
7 Embedded Operating Systems Claudio Scordino1, Errico Guidieri1, Bruno Morelli1, Andrea Marongiu2,3, Giuseppe Tagliavini3 and Paolo Gai1 1Evidence SRL, Italy 2Swiss Federal Institute of Technology in Zurich (ETHZ), Switzerland 3University of Bologna, Italy In this chapter, we will provide a description of existing open-source operating systems (OSs) which have been analyzed with the objective of providing a porting for the reference architecture described in Chapter 2. Among the various possibilities, the ERIKA Enterprise RTOS (Real-Time Operating System) and Linux with preemption patches have been selected. A description of the porting effort on the reference architecture has also been provided. 7.1 Introduction In the past, OSs for high-performance computing (HPC) were based on custom-tailored solutions to fully exploit all performance opportunities of supercomputers. Nowadays, instead, HPC systems are being moved away from in-house OSs to more generic OS solutions like Linux. Such a trend can be observed in the TOP500 list [1] that includes the 500 most powerful supercomputers in the world, in which Linux dominates the competition. In fact, in around 20 years, Linux has been capable of conquering all the TOP500 list from scratch (for the first time in November 2017). Each manufacturer, however, still implements specific changes to the Linux OS to better exploit specific computer hardware features. This is especially true in the case of computing nodes in which lightweight kernels are used to speed up the computation. 173 174 Embedded Operating Systems Figure 7.1 Number of Linux-based supercomputers in the TOP500 list. Linux is a full-featured OS, originally designed to be used in server or desktop environments. -

An "embedded system" is any computer system or computing device that performs a dedicated function or is designed for use with a specific embedded software applica tion. Embedded systems may use a ROM-based operating system or they may use a disk-based system, like a PC. But an embdddbedded sys tem is no t usa ble as a commercillially v ibliable substitute for general purpose computers or devices. 3 Aspects of embedded system design 4 Metrics •Performance can be measured in multiple ways –Latency vs. throughput –Average vs. worst-case vs. best-case –Peak vs. sustained •Power/energy –Power consumption is important for heat generation –Energy consumption is important for battery life –ItIntegra tdted me titrics suc h as Energy-De lay Pro duc t (EDP) •Cost –Des ign time vs. life time •Reliability –Avail a bility, depen da bility, performabilit y 5 Hardware/software codesign •Goals –Optimizing design process –Oppggtimizing design •Tasks –Cospecificationand comodeling –Codesign –Cosynthesis, optimization, interfacing –Verification 6 Codesign flow 7 What makes a good Embedded OS? Modular Scalable Configurable Small footprint CPU support Device drivers etc,,, etc, etc... 8 What is Real Time? “A real time system is one in which the correctness of the computations not only depends upon the logical correctness of the computation but also upon the time at which the result iddIfthtiititfthtis produced. -

Indeed new interfaces have cropped up to support them in a fashion resembling early GPUs, and some vendors have even opted to try to use DRM/GEM APIs for their devices. This talk will start with a background of what FPGAs are, how they work, and where they’re currently used. Because the audience is primarily people with graphics/display background, I will make sure to cover this well. It will then discuss the existing software ecosystem around the various usage models with some comparison of the existing tools. If time permits, I will provide a demo comparing open tools vs. closed ones. The goal of the talk is to find people who have lived through DRI1 days and are abletohelp contribute their experience (and coding) toward improving the stack for the future accelerators. -
