vProto - utilizes a human-perceptible State Machine and generates C++ code based on it to facilitate state transitions when parsing incoming data. It's extremely convenient for parsing existing protocols as well as describing custom ones. It's designed to work with any data fragmentation (data can arrive even byte by byte), which is highly relevant for the TCP protocol.
vSyn - transfer (translator) C language to Verilog. The development of algorithms in the C language is significantly simpler, more compact, and faster than in hardware description languages (Verilog, VHDL, SystemC, etc).
An automated process of transferring C logic to the hardware level is a highly effective approach in implementing complex and large projects on PLDs (Programmable Logic Devices) FPGA:
vSwitch is a hardware solution that allows FPGA-based packet management in Ethernet 10GBase-T/1000Base-T/100Base-T networks. Package management is carried out using FPGA, enabling operation at channel speed without packet loss.
