DVB-GSE IPv4/IPv6 Encapsulator
High-throughput, low-latency encapsulator IP cores for building DVB-GSE systems. The IP Core Worx DVBGSE IP cores have been optimised for high performance, and also for DVB-S2/-T2/-C2 implementations that have strict resource/area constraints; for example, FPGA-based systems.
Features
- GSE fragmentation & encapsulation of IPv4/IPv6 packets
- Designed for high throughput1 and low latency
- Supports GSE packet header types for no labels, 6 byte labels, label reuse, for label-based filtering
- Parameterisable MTU’s and SRAM/buffer sizes
- Low (logic and SRAM) resource usage
- Support for both 16200b and 64800b BBFRAME’s, and all DATA FIELD sizes
- AXI4-Stream (8-bit) Interconnect
- Wishbone (SPEC B4) interface for control and packet/device statistics
- Includes BBFRAME generator, stream MUX & scheduler, and padding & scrambling cores
- Robust exception handling and with rapid recovery from exceptions (due to overflows & invalid input data)
- FPGA-proven with Xilinx and Microsemi devices
Deliverables
- Netlist or synthesisable RTL source code in VHDL
- Comprehensive verification test bench and vectors in VHDL
- User guides and documentation for integration & configuration
- Top-level entity for a CCM-only system, to aid with evaluation and rapid-prototyping
