Operation Systems and Middleware

Operation Systems The key part for our development platforms are our expertise and experience in the integration and utilization of a full reach operation systems. We believe that the age of naked microcontrollers running the customer applications without operation systems is something of the past, highly emphasized by the fact of cost down of the ARM architecture (32 bits) and the general requirements for much functionality in the system.

We use Linux as our main operation system; our expertise on it allows us to keep in a strong position regarding our competitors in terms of time to market, price since it is free, extensive set of functionalities, high software quality thanks to the extensive community and user friendly.

We understand that Linux is too big for very deep embedded applications, so in that cases we use a very light Real Time Operation System (RTOS) provided by the Open Source community. We use the best alternative in the market under the free royalties’ license for embedded applications, with a high quality code and much functionality.

We are very confident that giving to our valuable customer a best in class operation system for their applications, the satisfaction will be complete in terms of quality, response time, real time if required, and price.

lwIP A Lightweight TCP/IP stack

lwip A Lightweight TCP/IP stackOne of the most important middleware is the TCP/IP stack. In full operation systems like Linux, Windows, Android, iOS, etc. the stack is already integrated, but in tiny real time operation systems, like FreeRTOS,FreeRTOS, ChibiOS/RT, etc. usually the TCP/IP stack in not integrated.

The TCP/IP model (Transmission Control Protocol/Internet Protocol) is a descriptive framework for the Internet Protocol Suite of computer network protocols created in the 1970s by DARPA.

FatFs Generic FAT File System Module

FatFs Generic FAT File SystemThe middleware is a fundamental part of any electronic embedded development. In CISIUM we have adopted FatFs is a generic FAT file system module for small embedded systems.

File Allocation Table (FAT) is the name of a computer file system architecture and a family of industry standard file systems utilizing it. The FAT file system is technically relatively simple yet robust. It offers reasonably good performance even in light-weight implementations and is therefore widely adopted and supported by virtually all existing operating systems for personal computers. This makes it a well-suited format for data exchange between computers and devices of almost any type and age from the early 1980s up to the present. Read more ...

FreeRTOS

freeRTOSIn the electronic development of embedded systems, CISIUM always is searching for the most appropriated RTOS for our customers. We have integrated the FreeRTOS in our development platform, an OS ranked by 8 over 10 in CISIUM. We have confirmed the memory footprint in FLASH is small 6KBy to 9KBy, and in RAM is medium 2KBy to 3KBy. We like form it the availability for many ports, how clean is the source code, the wide support and it is complete open source, royalty free.

FreeRTOS includes official ports to 26 architectures and receives more than 77,500 downloads a year. It is a popular, portable, open source, royalty free, mini Real Time Kernel - a free to download and free to deploy RTOS that can be used in commercial applications without any requirement to expose your proprietary source code.

Keil RTX Real-Time Operating System

Keil RTXA RTOS is a key piece in whatever modern electronic embedded design. With the current trend of very powerful microcontrollers, like LPC10 family from NXP (Cortex-M0), with a sub 1 USD range, makes sense to use RTOS in the development, for sort development time, reutilization and scalability.

The Keil RTX is a royalty-free, deterministic Real-Time Operating System designed for ARM and Cortex-M devices. It allows you to create programs that simultaneously perform multiple functions and helps to create applications which are better structured and more easily maintained.

Micrium µC/OS-II

Micrium µC/OS-IIWe have a wide experience in the integration and utilization of Micrium µC/OS-II, an excellent property Real Time Operation System.

Some say that µC/OS-II is simple enough for use by a hobbyist, the fact is that Micrium's strict standards were instrumental in creating a Validation Suite for µC/OS-II. As a result, it is successfully implemented in some of the highest level safety-critical devices, including those certified for avionics DO-178B Level A, and EUROCAE ED-12B, medical FDA pre-market notification (510(k)), and pre-market approval (PMA), and SIL 3/SiL4 IEC for transportation and nuclear systems.
