The GRHSSL IP Core is a versatile and highly configurable high-speed serial link controller written in VHDL, capable of implementing a SpaceFibre IP Core (GRSPFI), a WizardLink IP Core (GRWIZL), or both within a single solution.
GRHSSL is a highly configurable IP that can instantiate a SpaceFibre controller, a WizardLink controller or both. Both controllers share a DMA engine that handles the communication between the IP and external memory via hardware descriptors. GRHSSL shall be connected to a SerDes macro, that can be located either on-chip or externally. Adapters for AMBA AHB 2.0 and AXI 4 are available.
Additionally, the SpaceWire router can be integrated with the SpaceFibre controller. SpaceFibre ports can be connected to the internal FIFO ports of the SpaceWire router to bridge between SpaceWire and SpaceFibre traffic. SpaceWire data from/to multiple payloads can be aggregated in a single SpaceFibre High Speed Serial Link, all without software intervention.
