C (programming Language)
C (''pronounced like the letter c'') is a General-purpose language, general-purpose computer programming language. It was created in the 1970s by Dennis Ritchie, and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs. It has found lasting use in operating systems, device drivers, protocol stacks, though decreasingly for application software. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the measuring programming language popularity, most widely used programming languages, with C compilers avail ...

MicroC/OS-II
Micro-Controller Operating Systems (MicroC/OS, stylized as μC/OS) is a real-time operating system (RTOS) designed by Jean J. Labrosse in 1991. It is a priority-based preemptive real-time kernel for microprocessors, written mostly in the programming language C. It is intended for use in embedded systems. MicroC/OS allows defining several functions in C, each of which can execute as an independent thread or task. Each task runs at a different priority, and runs as if it owns the central processing unit (CPU). Lower priority tasks can be preempted by higher priority tasks at any time. Higher priority tasks use operating system (OS) services (such as a delay or event) to allow lower priority tasks to execute. OS services are provided for managing tasks and memory, communicating between tasks, and timing. History The MicroC/OS kernel was published originally in a three-part article in Embedded Systems Programming magazine and the book ''μC/OS The Real-Time Kernel'' by Labrosse. He ...

OpenCL
OpenCL (Open Computing Language) is a framework for writing programs that execute across heterogeneous platforms consisting of central processing units (CPUs), graphics processing units (GPUs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs) and other processors or hardware accelerators. OpenCL specifies programming languages (based on C99, C++14 and C++17) for programming these devices and application programming interfaces (APIs) to control the platform and execute programs on the compute devices. OpenCL provides a standard interface for parallel computing using task- and data-based parallelism. OpenCL is an open standard maintained by the non-profit technology consortium Khronos Group. Conformant implementations are available from Altera, AMD, ARM, Creative, IBM, Imagination, Intel, Nvidia, Qualcomm, Samsung, Vivante, Xilinx, and ZiiLABS.

NonStop OS
NonStop is a series of server computers introduced to market in 1976 by Tandem Computers Inc., beginning with the NonStop product line, which was followed by the Hewlett-Packard Integrity NonStop product line extension. It is currently offered by Hewlett Packard Enterprise since Hewlett-Packard Company's split in 2015. Because NonStop systems are based on an integrated hardware/software stack, HPE also developed the NonStop OS operating system for them. NonStop systems are, to an extent, self-healing. To circumvent single points of failure, they are equipped with almost all redundant components. When a mainline component fails, the system automatically falls back to the backup. These systems are often used by banks, stock exchanges, payment applications, retail companies, energy and utility services, healthcare organizations, manufacturers, telecommunication providers, transportation and other enterprises requiring extremely high uptime.

TRON Project
TRON (acronym for The Real-time Operating system Nucleus) is an open architecture real-time operating system kernel design. The project was started by Professor Dr. Ken Sakamura of the University of Tokyo in 1984. The project's goal is to create an ideal computer architecture and network, to provide for all of society's needs. The Industrial TRON (ITRON) derivative was one of the world's most used operating systems in 2003, being present in billions of electronic devices such as mobile phones, appliances and even cars. Although mainly used by Japanese companies, it garnered interest worldwide. However, a dearth of quality English documentation was said to hinder its broader adoption. The TRON project was integrated into T-Engine Forum in 2010. Today, it is supported by popular Secure Socket Layer (SSL) and Transport Layer Security (TLS) libraries such as wolfSSL. Architecture TRON does not specify the source code for the kernel, but instead is a "set of interfaces and design ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
