The CyaSSL embedded SSL library is a lightweight SSL library written in ANSI C and targeted for embedded and RTOS environments, primarily because of its small size, speed, and feature set. It is commonly used in standard operating environments and cloud services as well because of its royalty-free pricing and excellent cross platform support. CyaSSL supports industry standards up to the current TLS 1.2 and DTLS 1.2 levels, is up to 20 times smaller than OpenSSL, and offers progressive ciphers such as HC-128, RABBIT, and NTRU.
Rateless-coded Transport is a set of applications that use ground-breaking error correcting codes technology. They support fast reliable transmission over UDP, live content streaming and Internet multicast trees, duplex firewall transparency, ultra-fast reliable transport for WANs (up to 40-times faster than TCP), and optimal peer-to-peer multi-source download protocols.
db.* is a database management system (DBMS) designed to provide powerful, flexible, high-performance capabilities for developing embedded database applications. By combining the network and relational model technologies in a single system, it lets you organize and access information efficiently, regardless of the complexity of the data. The database has a very small footprint and because it is possible to use the network model to store some of the data, it can be very fast. It is also well-documented and quite simple to learn because of its C-based API.
elfrc is a program which can turn arbitrary files into ELF object files which can then be linked into your program directly and accessed via simple, user-defined symbol names. Since this is much more effective than turning a binary file into a C array and then compiling that, it's possible to embed even huge (a few hundred megabytes) files directly into the executable and then access the data in constant time without making the compiler or linker eat loads of memory.
The CRT X-Y Library (libcrtxy) allows you to write vector-based video games (like Asteroids, Lunar Lander, and Battlezone from the 1970s and 80s). The end-user (and/or packager of your software) determines how lines are rendered, depending on the capabilities of their system. This choice includes anti-aliasing, alpha blending, blurring, and even the display size and depth. Fixed-point math is used, and sine and cosine trigonometric functions (using look-up tables) are provided. The library is based on libSDL and uses SDL as the video backend.
nMicrocoder is an ncurses EDA tool to write microcode. Basically, it is a stripped down spreadsheet program that lets you fill a table with "0", "1", and "-", and gives you compile-ready verilog code in return. It was written as an alternative to full spreadsheet programs. It is known to run on Linux, IRIX, and Solaris, unless ncurses 5.3 is installed.
yaSSL is a C++ based SSL library for embedded and RTOS environments, designed for individuals who prefer to use the C++ language. For a C-based solution, please see CyaSSL. yaSSL supports the industry standards up to TLS 1.2, and also includes an OpenSSL compatibility interface.
