SpaceWire link controller with SpaceWire RMAP support and AMBA host interface
The GRSPW2 core implements a SpaceWire link controller with SpaceWire RMAP support and AMBA host interface.
Overview
The GRSPW2 core implements a SpaceWire link controller with SpaceWire RMAP support and AMBA host interface.
The GRSPW2 core implements a SpaceWire link controller with RMAP support and AMBA host interface. The core complies to the SpaceWire standard (ECSS-E-ST-50-12C) with the protocol identification extension (ECSS-E-ST-50-51C) and RMAP protocol (ECSS-E-ST-50-52C). Receive and transmit data is autonomously transferred between the SpaceWire Codec and the AMBA AHB bus using DMA transfers. Through the use of receive and transmit descriptors, multiple SpaceWire packets can be received and transmitted without CPU involvement. The GRSPW2 control registers are accessed through an APB interface. For critical space applications, a fault-tolerant (FT) version of GRSPW2 is available with full SEU protection of all RAM blocks.
