Newlib
Newlib is a C standard library implementation intended for use on embedded systems. It is a conglomeration of several library parts, all under free software licenses that make them easily usable on embedded products. It was created by Cygnus Support as part of building the first GNU cross-development toolchains. It is now maintained by Red Hat developers Jeff Johnston and Corinna Vinschen, and is used in most commercial and non-commercial GCC ports for non-Linux embedded systems. System Calls The section System Calls of the Newlib documentation describes how it can be used with many operating systems. Its primary use is on embedded systems that lack any kind of operating system; in that case it calls a board support package that can do things like write a byte of output on a serial port, or read a sector from a disk or other memory device. Inclusion Newlib is included in commercial GCC distributions by Atollic, CodeSourcery, Code Red, KPIT, Red Hat and others, and re ...

BSD Libc
The C standard library, sometimes referred to as libc, is the standard library for the C (programming language), C programming language, as specified in the ISO C standard.International Organization for Standardization, ISO/International Electrotechnical Commission, IEC (2018). ''C17 (C standard revision), ISO/IEC 9899:2018(E): Programming Languages - C §7'' Starting from the original ANSI C standard, it was developed at the same time as the C POSIX library, which is a superset of it. Since ANSI C was adopted by the International Organization for Standardization, the C standard library is also called the ISO C library. The C standard library provides macro (computer science), macros, Data type, type definitions and Function (computer programming), functions for tasks such as character string (computer science), string manipulation, mathematical computation, input/output processing, memory management, and input/output. Application programming interface (API) Header files The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AIBO
AIBO (stylized as aibo, abbreviated as Artificial Intelligence RoBOt, homonymous with , "pal" or "partner" in Japanese) is a series of robotic dogs designed and manufactured by Sony. Sony announced a prototype Aibo in mid-1998, and the first consumer model was introduced on 11 May 1999. New models were released every year until 2006. Although most models were dogs, other inspirations included lion cubs and space explorers. Only the ERS-7, ERS-110/111 and ERS-1000 versions were explicitly a "robotic dog", but the 210 can also be considered a dog due to its Jack Russell Terrier appearance and face. In 2006, AIBO was added into the Carnegie Mellon University Robot Hall of Fame. On 26 January 2006 Sony announced that it would discontinue AIBO and several other products in an effort to make the company more profitable. Sony's AIBO customer support was withdrawn gradually, with support for the final ERS-7M3 ending in March 2013. In July 2014, Sony stopped providing repairs for AIBO ...

Runtime Library
A runtime library is a library that provides access to the runtime environment that is available to a computer program tailored to the host platform. A runtime environment implements the execution model as required for a development environment such as a particular programming language. A runtime library may provide basic program facilities such as for memory management and exception handling. A runtime library is an artifact of the design of the toolchain used to build the program not inherently required by the host operating system or the programming language in which the program is written. The toolset is designed to abstract aspects of the host platform often to simplify tool development. The toolchain builds a program to depend on a runtime library and to use it while the program is running at program run-time. The runtime library may directly implement runtime behavior, but often it is a thin wrapper on top of operating system facilities. For example, some langua ...

Cygwin
Cygwin ( ) is a free and open-source Unix-like environment and command-line interface (CLI) for Microsoft Windows. The project also provides a software repository containing open-source packages. Cygwin allows source code for Unix-like operating systems to be compiled and run on Windows. Cygwin provides native integration of Windows-based applications. The terminal emulator mintty is the default command-line interface provided to interact with the environment. The Cygwin installation directory layout mimics the root file system of Unix-like systems, with directories such as /bin, /home, /etc, /usr, and /var. Cygwin is released under the GNU Lesser General Public License version 3. It was originally developed by Cygnus Solutions, which was later acquired by Red Hat (now part of IBM), to port the GNU toolchain to Win32, including the GNU Compiler Suite. Rather than rewrite the tools to use the Win32 runtime environment, Cygwin implemented a POSIX-compatible environment in t ...

Bionic (software)
Bionic is an implementation of the C standard library, developed by Google for its Android operating system. It differs from the GNU C Library (glibc) in being designed for devices with less memory and processor power than a typical Linux system. It is a combination of new code and code from FreeBSD, NetBSD, and OpenBSD released under a BSD license, rather than glibc, which uses the GNU Lesser General Public License. This difference was important in the early days of Android, when static linking was common, and since Bionic has its own application binary interface, it cannot be replaced by a different libc without breaking all existing apps. Bionic is a C library for use with the Linux kernel, and provides libc, libdl, and libm ( libpthread functionality is part of libc, not a separate library as on some other systems). This differs from the BSD C libraries that Bionic shares code with, because they require a BSD kernel. Original goals The original publicly stated goals for ...

Google Native Client
Google Native Client (NaCl) is a discontinued sandboxing technology for running either a subset of Intel x86, ARM, or MIPS native code, or a portable executable, in a sandbox. It allows safely running native code from a web browser, independent of the user operating system, allowing web apps to run at near-native speeds, which aligns with Google's plans for ChromeOS. It may also be used for securing browser plugins, and parts of other applications or full applications such as ZeroVM. Google first demonstrated the technology on 9 December 2011 by releasing several new Chrome-only versions of games known for their rich and processor-intensive graphics, including ''Bastion'' (no longer supported on the Chrome Web Store). Later Google released Portable Native Client (PNaCl), an architecture-independent compiled ahead-of-time version of NaCl. The general concept of NaCl (running native code in web browser) has been implemented before in ActiveX, but NaCl runs content in a sandbox ...

Glibc
The GNU C Library, commonly known as glibc, is the GNU Project implementation of the C standard library. It provides a wrapper around the system calls of the Linux kernel and other kernels for application use. Despite its name, it now also directly supports C++ (and, indirectly, other programming languages). It was started in the 1980s by the Free Software Foundation (FSF) for the GNU operating system. glibc is free software released under the GNU Lesser General Public License. The GNU C Library project provides the core libraries for the GNU system, as well as many systems that use Linux kernel, Linux as the kernel (operating system), kernel. These libraries provide critical APIs including ISO C11 (C standard revision), C11, POSIX.1-2008, Berkeley Software Distribution, BSD, OS-specific APIs and more. These APIs include such foundational facilities as open (system call), open, read (system call), read, write (system call), write, malloc, printf format string, printf, getaddrin ...

Keith Packard
Keith Packard (born April 16, 1963) is a software developer, best known for his work on the X Window System. Packard is responsible for many X extensions and technical papers on X. He has been heavily involved in the development of X since the late 1980s as a member of the MIT X Consortium, XFree86 and the X.Org Foundation. In 2011, O'Reilly awarded an open source award to Packard, as "the person behind most of the improvements made on the open source desktop in the last ten years at least." He is portrayed as one of the ''Faces of Open Source''. Career Packard gained a BA in mathematics from Reed College, Oregon in 1986. He worked at Tektronix, Inc. in Wilsonville, Oregon designing X terminals and Unix workstations from 1983 until 1988. He then moved to Cambridge, Massachusetts to work at the Massachusetts Institute of Technology X Consortium from 1988 to 1992, developing the X Window System reference implementation and standards as the senior member of a small team.

Cygnus Support
Cygnus Solutions, originally Cygnus Support, was founded in 1989 by John Gilmore, Michael Tiemann and David Henkel-Wallace to provide commercial support for free software. Its tagline was: ''Making free software affordable''. For years, employees of Cygnus Solutions were the maintainers of several key GNU software products, including the GNU Debugger and GNU Binutils (which included the GNU Assembler and Linker). It was also a major contributor to the GCC project and drove the change in the project's management from having a single gatekeeper to having an independent committee. Cygnus developed BFD, and used it to help port GNU to many architectures, in a number of cases working under non-disclosure to produce tools used for initial bringup of software for a new chip design. Cygnus was also the original developer of Cygwin, a POSIX layer and the GNU toolkit port to the Microsoft Windows operating system family, and of eCos, an embedded real-time operating system. In the 2001 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dietlibc
dietlibc is a C standard library subset released under the GNU General Public License Version 2, and proprietary licenses are also available. It was developed with the help of about 100 volunteers by Felix von Leitner with the goal to compile and link programs to the smallest possible size. dietlibc was developed from scratch and thus only implements the most important and commonly used functions. It is mainly used in embedded devices.
