CCSDS ECSS

The CCSDS/ECSS Spacecraft Data Handling IP cores represent a collection of cores that have been developed specifically for the space sector. These IP cores implement functions commonly used in spacecraft data handling and management systems. Supporting Software Libraries and EGSE equipment are available.

The cores implement international standards from organizations such as Consultative Committee for Space Data Systems (CCSDS), European Cooperation on Space Standardization (ECSS), and the former Procedures, Standards and Specifications (PSS) from the European Space Agency (ESA). Documentation of the spacecraft data handling IP cores can be found in the GRLIB IP Core User's Manual.

The spacecraft data handling IP cores cover the following functions:

• CCSDS/ECSS Telemetry Encoder
• CCSDS/ECSS Telemetry Encoder - Descriptor
• CCSDS/ECSS Telemetry Encoder - Virtual Channel Generation
• CCSDS/ECSS Telemetry Encoder - Virtual Channel Generation Input - AMBA
• CCSDS/ECSS Telemetry Encoder - Virtual Channel Generation Input - Packet Wire
• CCSDS/ECSS Telemetry Encoder - CLCW Receiver
• CCSDS/ECSS Telemetry Encoder - CLCW Multiplexer
• CCSDS/ECSS Telemetry Encoder - Geffe Generator
• CCSDS/ECSS Telemetry Receiver
• CCSDS/ECSS Convolutional Encoder and Quicklook Decoder
• CCSDS/ECSS Telecommand Decoder
• CCSDS/ECSS Telecommand Decoder - Hardware Commands
• CCSDS/ECSS Telecommand Decoder - UART

• CCSDS/ECSS Telecommand Decoder - COP-1
• CCSDS/ECSS Telecommand Transmitter
• CCSDS Time Manager - with datation and pulse generation
• CCSDS 121/123 Lossless Data Compression
• SpaceWire - CCSDS Unsegmented Code Transfer Protocol
• PacketWire Interface - acts as a master on the AMBA AHB bus providing remote control
• PacketWire Receiver - acts as master with DMA on AMBA AHB bus
• PacketWire Transmitter - acts as master with DMA on AMBA AHB bus
• PacketWire Receiver Interface - acts as a slave on the AMBA APB bus
• PacketWire Transmitter Interface - acts as a slave on the AMBA APB bus
• Packet Parallel Interface - acts as a slave on the AMBA AHB bus
• General Purpose Input Output - with pulse generation
• General Purpose Timer Unit- with external clock input, event outputs, and datation latch
• Reconfiguration Module
• Version and Revision information register

Lossless Data Compression

The SHyLoC CCSDS121 and CCSDS123 IP cores implements the CCSDS 121.0-B-2 and 123.0-B-1 standards for lossless data compression, respectively. The cores are available as stand-alone cores and are also delivered with an AMBA wrapper with a register interface and a DMA engine.
