    XLS

    XLS

    XLS: Accelerated HW Synthesis

    XLS is an open-source toolkit for building high-level hardware with a modern compiler stack that spans from a functional DSL to optimized IR and hardware generation. At the front end, DSLX lets you describe algorithms with strong typing and familiar control flow while remaining synthesis-friendly. The compiler lowers DSLX into a rich intermediate representation, applies aggressive optimization and scheduling passes, and can either JIT the design for software simulation or emit Verilog for FPGA/ASIC flows. A key idea is “software-style” iteration: fast, deterministic simulation via the JIT encourages test-driven development and property checking before committing to RTL. XLS also provides tooling for pipelining, state insertion, and formal equivalence checks between different stages, giving developers confidence as designs evolve. The result is a productive path from high-level specification to real hardware, without giving up control over latency, throughput, and area trade-offs.

    ProgramNet Designer

    ProgramNet Designer

    C++ cross plattform functional block programming

    With the help of the ProgramNet the user can develop plug-ins(called units) which can be connected with other units forming a net. The net has a form of a flow diagram. The resulted net can be executed in the ProgramNet for testing purposes or independently in the target platform as a final release. In order to execute a net the ProgramNet uses the kernel. The kernel executes automatically each unit in a separate thread and manages the data exchange between the units.

    PixelValue

    PixelValue

    Shows the color value and HTML code of a pixel under the mouse cursor

    A simple Windows console app that can show the RGB color values and HTML color code of a pixel under the mouse cursor when the user clicks somewhere on the screen. The results are stored as a table in a .html file, and displayed in the default web browser. It doesn't require any instalation, just start the .exe To start mouse click tracking press Shift, to stop tracking press Ctrl. The program will display a dot in the console for every mouse click tracked so far. To enable debugging information in the console (mouse cursor position, RGB value of the pixel under the cursor, HTML color code) press Alt. To disable it press Alt again. To save all the tracked mouse clicks to a table in a .html file (this file is called output.html, and is created automatically in the folder where the .exe file is currently located) and display it in your default web browser, press the middle mouse button (the mouse wheel). That's pretty much it...:D You are free to use or share it as you like.
