A software framework for Linux device drivers aimed at supporting controls and data acquisition hardware. ZIO supports sub-nanosecond timestamps, block-oriented input and output and transport of meta-data with the data samples. Users can change the buffer type and trigger type associated with a device at run time, and all of devices, triggers and buffers are easily implemented as add-on modules.

The PF_ZIO implementation, currently in beta status, implements a network interface to the ZIO transport, which allows each I/O channel to generate or receive network frames. Applications see the network of devices and can talk with several of them from the same socket. We support SOCK_STREAM, SOCK_DGRAM and SOCK_RAW.

YAM is a micro-controller core aiming at simple yet fast IO sequencing with integer processing capabilities. YAM parameters may be assigned to fit many applications. The data width is scalable from 8 to any value (like 32 or larger) size.

xTCAprojects shows the MTCA and uTCA boards that are developed in the Open Hardware Repository context. Keywords: MTCA.4, uTCA, AMC, MCH.

Control of instrumentation over a White Rabbit network. Define and implement a standardized communication protocol for instrumentation over a White Rabbit network (precise synchronization and timestamping; remote control and test sequence programming; message exchanging and event distribution).

WRAP, White RAbbit Pluggable, is a plug-in board providing easy-to-use WR functionality. Among others it provides direct 10MHz and PPS (pulse per second) outputs.

wbgen2 is a tool for generating VHDL/Verilog cores which implement Wishbone bus slaves with certain registers, memory blocks, FIFOs and interrupts. The input is a C-like syntax file with an abstract description of what do we want to have in the slave. As a result, we get:

- Automatically allocated memory layout

- VHDL/Verilog code for the slave module

- C header files for driver development - Nice HTML documentation
