AITIA's 1 Gb/s high throughput TCP sender core
We developed this core to ensure lossless transfer of processed frames between the FPGA and the receiving monitor PC-s. Therefore the main goal was to create a hardware optimized implementation to maximize performance and liability.
Features:
- RFC 675/RFC 793 compliant implementation
- Source code available for further development!
- Fabric side interface is configurable for different 1G MAC modules
- User side interface is configurable for different applications (64 bit@125MHz by default)
- 8/16/32/64 Kbyte selectable internal buffer for retransmissions
- basic ARP protocol implementation (request,response)
- implements modified slow start, and keep alive sending
- implements hardware optimized fast retransmit, and conguestion avoidance algorithms
- tested on CBOARD/C-GEP 20 with SFP modules, and IBM compatible PC-s running Windos and Linux systems
- Sample application available
