The GRHSSL IP is a highly configurable high-speed serial link controller, described in VHDL. It can implement:
* SpaceFibre controller (GRSPFI)
* WizardLink controller (GRWIZL)
* ...or both (GRHSSL)
Thanks to the DMA engine, receive and transmit data are autonomously transferred between the serial link and the on-chip bus, which in turn can be either AMBA AHB or AXI.
