3. NPAP Functionality Description NPAP is a complete subsystem of a high-performance programmable-logic based, standalone network stack featuring transparent handling of complete TCP/IPv4 and UDP/IPv4 protocol tasks, e.g. packet encoding, packet decoding, acknowledge generation, link supervision, timeout detection, retransmissions and fault recovery. NPAP supports complete automatic connection control including tear up and tear down. Compute and manage retransmission timers as in RFC 6298. Transparent checksum generation and checksum checking, integrated flow control. RFC 9293 compatibility (TCP/IPv4 stack for Windows and Linux). Depending on the project’s needs, deliverables can be: HDL source code or netlist Integrated FPGA system implementation Testbenches and scripts for real-life testing Comprehensive documentation and interfacing guide Development & design-in support NPAP has been optimized to ensure the best bandwidth-delay product performance for your application. To guarantee delivery of full performance and reliability Team MLE will support you in all engineering aspects: System-level architecture design where aspects such as mapping ingress / egress data streams to TCP sessions, or handling TCP’s congestion control, or optimizing the bandwidth-delay-product are handled in order to meet system-level bandwidth and latency requirements. Chip-design, i.e. managing chip resources, interfacing with the Multi-Gigabit Transceivers (MGT), handling on-chip streaming (such as AXI beats) while integrating NPAP into your FPGA or ASIC device on your target hardware.
