IP Core for medium data rate PDT, compliant with CCSDS 131.2-B-1 standard.
The IP Core for Medium Data Rate PDT implements a Serially Concatenated Convolutional Coding (SCCC) scheme for telemetry application, which functionality is compliant with CCSDS 131.2-B-1 (Flexible advanced coding and modulation scheme for high rate telemetry applications) standard. The transmitter makes use of a large variety of modulation schemes (including QPSK, 8-PSK, 16-APSK, 32-APSK and 64-APSK) and a wide range of coding rates.
The CCSDS Telemetry Transmitter IP core ports can be divided into the following interfaces, based on the functionality they are related to:
- Input data interface
- Output data interface
- Configuration and status interface
- LUT loader interface
- Clock, reset and enable
The architecture was conceived with flexibility in mind. In order to easily adapt the IP core to many different use cases, it is provided with a complete set of hard configuration parameters, which allow enabling/disabling features of the processing, as well as optimizing the architecture in terms of performance/complexity trade-off. The hard configuration parameters are all accessible via the top-level generics.
Verification and validation
The IP Core has been extensively verified against a Matlab golden reference model. Validation was performed on RTG4 and BRAVE NG-MEDIUM development boards.
The IP Core has been successfully mapped to the following target technologies:
- Microsemi RTAX2000
- Microsemi ProASIC RT 3000L
- Microsemi RTG4
- Xilinx Virtex5-QV
Special licensing restrictions
None. The IP Core can be licensed to ESA Member States for ESA's own requirements.
