ztex is a firmware Kit with a corresponding Driver API which is especially designed for the ZTEX Modules but which should work with all other EZ-USB based hardware. The Firmware Kit is written in C and assembled using a powerful macro processor. This allows you to specify all required settings using by a few commands. The necessary USB descriptors and the descriptor handling routines are generated automatically. The package runs under Linux and Windows (porting to other operating systems should be no problem). The Java driver API allows the development of platform-independent device drivers.
CoreTML framework is a template configuration system. It is based on the idea of parametrized templates that are created by inserting special content into source code files. These templates can later be used to generate output files depending upon parameters chosen by the user. CoreTML framework was created primarily to provide a platform for the design and deployment of semiconductor IP cores on a hardware description language (HDL) level (i.e. VHDL or Verilog).
MBSL (MicroBlaze Simple Linux) is a set of Makefile scripts to create an image of a Linux-based OS for the Xilinx MicroBlaze (FPGA) soft processor. It provides very simple package management that allows you to customize the resulted image. The purpose is to just type 'make build install' and get the configured image.
fpgatools is a toolchain for programming flexible programmable gate arrays (FPGAs). The only supported chip at this time is the xc6slx9, a cheap (circa $10 U.S.) but powerful 45nm-generation chip with about 2400 LUTs, block ram, and multiply-accumulate devices. The principles of fpgatools are to reach the maximum physical performance of the chip, to provide fast development cycles, to be an independent toolchain which only depends on other Free Software, and to be a lightweight C implementation without a GUI.
