Open Source VHDL/Verilog Hardware Platforms - Page 2

Documentation, simulator, compiler, and Verilog implementation of a completely open-architecture graphics processing unit. This design is intended for academic and commercial purposes. The first step is to develop a detailed GPU simulator and compiler. The second step is to implement the GPU in synthesizable Verilog. The third step is to develop a feedback loop between the simulator and implementation, allowing power, performance, and reliability aspects of the hardware to feed back into ever more detailed and accurate simulations of a complete GPU.

Revenue will be invested per the discretion of the Facilitator and an advisory board. By contributing to this project, you agree to these terms.

OpenVGA is an free and open FPGA-based implementation of a VGA compatible graphics adapter, and utilising low-cost hardware. The project includes the PCB schematic and artwork, Verilog HDL, firmware assembly code, and driver source code.

This project introduces new FPGA architectural tools and Linux OS modifications that aid in supporting Dynamic Partial Reconfiguration (DPR) on FPGAs for concurrent control. It shows that control systems benefit from hardware concurrency, meaning that by moving the control intelligence into hardware, the negative effects inherent to threads and their scheduler are minimized. This leaves software with the role of a high-level administrator rather than an executor, thereby eliminating unnecessary bottlenecks. The tools described in this project enable the hardware engineer to develop DPR-FPGA systems more effectively for rapid control system development.

SmGen is a finite state machine (FSM) generator for Verilog. On the other hand, it is not an FSM entry tool. The input is behavioral Verilog with clock boundaries specifically set by the designer. SmGen unrolls this behavioral code and generates an FSM from it in synthesizable Verilog. Clock boundaries are explicitly provided by the designer so there is good control on the expected timing

HW(VHDL) and SW of logic analyzer and On-Chip-Verification(OCV) for Value Change Dump(VCD) file format that exported to seemd SystemC ,ModelSIM, and many other EDA tools. Very easy and Simple.

The HDL Complexity Tool parses large complex hardware projects' source code to produce useful complexity results. GOALS: 1)Practical, effective and simple 2) Integrates with existing design flows 3) Used on real projects 4) Based on existing research

The SBus is a family of high-speed packet-based databus standards, suitable for both networking and interdevice communication. They are optimized for high data density transactions. This project creates and documents the standards, schematics, and driver

This project contains the material discussed in my PhD dissertation, entitled "Hardware/Software Design of Dynamic Real-Time Schedulers for Embedded Multiprocessor Systems." The source code is available in the SVN repository: https://sourceforge.net/p/xrt/code/6/tree/trunk/ and consists in two folders: 1) /X-RT : A portable multiprocessor scheduling framework supporting scheduling periodic real-time tasks according to the G-EDF (Global Earliest Deadline First) scheduling platform. Current version supports major POSIX systems (Linux, QNX). 2) Hardware_GEDF_Scheduler: is a hardware implementation in VHDL (targeting FPGAs) of the G-EDF multiprocessor scheduling policy.

Yet Another DLX based Architecture System On a Chip (YADASOC) is a RTL Verilog implenetation of a DLX based CPU and subsystems.

This project was moved to https://gitlab.c3sl.ufpr.br/roberto/cmips The code here is no longer up to date. The VHDL model mimics the pipeline design described in Patterson & Hennessy's book (Computer Organisation and Design) and is an almost complete implementation of the MIPS32r2 instruction set. The TLB and assorted control registers will be included soon (as of fev 2015). The model was synthesized for an Altera EP4CE30F23. The model uses up 15% of combinational blocks and 5% logic registers.

Inane's not a NES emulator. It is a reimplementation of the original NES hardware in VHDL with the goal of making it fully synthesize in hardware.

The “lpACLib” library contains the VHDL description of accurate and approximate versions of several arithmetic modules (like adders and multiplier of different bit-widths) and accelerators. Moreover, it also provides the corresponding software behavioral models/implementations developed in C and MATLAB to enable quality characterization. Besides our novel designs, it also contains implementations for several state-of-the-art arithmetic modules and their approximate versions. This open-source library facilitates research and development in approximate computing at higher abstraction levels, and to facilitate reproducible research and comparisons.

m4-la is a Logic Analyzer written in VHDL for the Xilinx ML403 Development board featuring the Virtex4 FPGA. The user interface is written in C for Windows32 based platforms. Xilinx ISE and EDK tools compile the VHDL and MS Visual Studio compiles the UI.

Picode is the ultimate VHDL picode 16 to 32 bits controller. It is described in only one entity and is implementable in standard FPGAs. It has it own compiler. Picode is designed to take only one or two clock cycle duration per instruction.
