CCSDS/ECSS Spacecraft Data Handling IP Cores

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.

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).

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 - CLCW Transmitter
  • CCSDS/ECSS Telecommand Transmitter
  • CCSDS Time Manager - with datation and pulse generation
  • 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
  • Version and Revision information register

Implementation characteristics

The cores are portable and can be implemented on most FPGA and ASIC technologies, and have been tested for Microsemi/Actel RTAX and RT ProASIC3, and Xilinx Virtex FPGA technologies.

The cores are available in VHDL source code and, when applicable, use the plug&play configuration method described in the GRLIB User's Manual.

Licensing

  • The TMTC licence covers basic IP cores, with the upper TM and TC layers implemented in software.
  • The TMTC+ licence covers additional IP cores for implementing part of the upper TM and TC layers in hardware.
  • The TMTC++ licence covers additional IP cores for implementing TM and TC test equipment.

Missions and devices

The spacecraft data handling IP cores have been used in several satellite developments and ASIC devices. The following is a list of recent missions and devices:
