The next generation of the linux kernel , evolving from a motholic kernel to the new sleek efficient exokernel. The power is in the application's hands... The newest release of exolu (coming soon..) will include a compiler , bootloader and object orient

Ela, functional language

Ela is a modern programming language that runs on CLR and Mono. The language is dynamically (and strongly) typed and comes with a rich and extensible type system out of box. It provides an extensive support for the functional programming paradigm including but not limited to - first class ... [More] functions, first class currying and composition, list/array comprehensions, pattern matching, polymorphic variants, thunks, etc. It also provides some imperative programming features. Ela supports both strict and non-strict evaluation but is strict by default. The current language implementation is a light-weight and efficient interpreter written fully in C#. The interpreter was designed to be embeddable and has a clear and straightforward API. [Less]

jpeg2000

ABSTRACT CECÍLIO, Pablo Lira. A solution for image capture, compression and transmission by using jpeg2000 in an embedded system. 2009. 61f. Trabalho de Conclusão de Curso (Graduação) – Faculdade de Engenharia de Computação, Centro de Ciências Exatas, Ambientais e de Tecnologias ... [More] , Pontifícia Universidade Católica de Campinas, Campinas, 2009. The size of the image handled by a program affects its performance directly: the larger the image, the lower the performance in the same hardware. The system approached by the present monograph is run in an embedded Analog Devices system, which captures, compresses, and sends images to a PC through a connection under the Zigbee protocol. As the wireless transmission of Xbee devices is very slow, the objective of this system is to decrease the time of image transmission through image compression before their transmission takes place. The system was developed in two main modules: the former is run in the embedded system and written in C/C++ and Assembly; the latter is run in a PC and written in C# and SQL. The system that is run in the embedded system captures images through a CDD camera. Next, it compresses them in the JPEG2000 format (whose features are compression speed and small use of computer resources) and sends them through the Zigbee connection (used in the market by several low-cost devices, in addition to being a high scalability protocol). Prototyping was the methodology in use for the development of such system. The system evaluation showed that in spite of images being frequently corrupted during the transmission, a significant decrease of ten seconds in transfer speed was attained because of the compression. Indexing terms: Image compression. Wireless information transfer. Embedded system. Image storage in database. see more details at http://code.google.com/p/jpeg2000/source/browse/trunk/TCC/entregas/TCC2/Monografia_final.pdf The source code is available at: http://code.google.com/p/jpeg2000/source/browse/trunk/TCC/ This project will use - jpeg2000 for image encoding - NSC/PAL analogic camera for image capture - Ez-kitLite evaluation board with bf533 processor as main board for image processing and image transmission - Xbee for image transmission working in 115200bps [Less]

sync-sqlite3

This project provides a choice of handling synchronizing problem when your using Sqlite3 even in the embeded system. It provides a set of api to let users record,synchronize data in the sqlite3 database .This project aims at the one central database and many data node's mode.If your application ... [More] needs functions like this.Just download and use it. 这个是一个用于Sqlite3数据库数据同步的系统，使用了Sqlite3的hook，记录被修改的数据并通过网络同服务器来和中心数据库同步。本项目主要提供了两个模块，一个是客户端的数据库同步API，它有几个依赖的库，包括sqlite3,uuid,curl,json,要编译到您的系统上，请首先在您的系统上编译好这几个类库，如果之前没有的话。另一个是同步服务，目前只提供了简单的数据发送和接受然后转换到中心数据库中的功能，管理功能后续推出。它的安装很简单，只需要jsr311的类库和一个tomcat这样的web container就可以了，当然中心数据库的jdbc驱动是不可缺少的。 [Less]

ezfb

Ezfb(easy frame buffer) is a small and simple 2D graphic library based on frame buffer. You can create graphic application easily through this library even in embeded system.

milestag-c18

This is an implementation of the Milestag Lasertag protocol (most likely just a subset) in Microchip's C18. The target processor is a PIC18f2420. The goal is to have full duplex on one chip with a selection of either Milestag or Laser Challenge protocol (the latter for backwards ... [More] compatability). The system will also have sound provided by an ISD1700 series Chipcorder with the ability to re-program in-circuit under PC control using an RS-232 interface. The circuit will be designed such that the micro-controller can be reprogrammed in-circuit. [Less]
