Actel Corporation 
Part Number : Spacewire
Overview :
The GRSPW core implements a Spacewire Codec with RMAP support and AMBA host interface. The core implements the Spacewire standard with the protocol identification extension (ECSS-E- 50-12 part 2) and RMAP protocol draft C. 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 GRSPW control registers are accessed through an APB interface. For critical space applications, a fault-tolerant (FT) version of GRSPW is available with full SEU protection of all RAM blocks.
Features : - GRSPW provides an interface between an AHB bus and a Spacewire network
- Implements the Spacewire standard with the protocol identification extension (ECSS-E-50-12 part 2)
- Optional Remote Access Memory Protocol (RMAP) command handler
- Data transferred through DMA channels using an AHB master interface
- Core can be extended to use separate DMA channels for specific protocols
- 3 clock domains - AHB interface (system clock), transmitter and receiver
- Core supports byte addressed 32-bit big-endian host systems
- Support for Fusion, IGLOO, ProASIC3/E, Axcelerator and RTAX-S Product Families
