The concept of SDR is very encouraging for the development of state-of-the-art physical layer functionality, because software programming allows much faster development cycles. SDR development has so far mostly been limited to non-real-time physical development, because of slow sequential execution of algorithms on CPUs in comparison to ASIC, ASIP or FPGAs. With the HW accelerated SDR approach, ORCA brings computationally intensive processing units like FEC encoder, IFFT and pulse shaping filtering down to the FPGA which increases computational throughput.

The following ORCA offers include improvements on the physical layer, the design-time composition of MAC and PHY and further the integration of PHY and upper layer protocols.

The different latency, throughput, and power consumption requirements of wireless services ask for distinct PHY, MAC and upper layer mechanisms, each to be run in different types of computing platforms (see deliverable 2.2). While the advanced flexibility brought by SDR is part of the answer to such diversity in traffic demands, it cannot be fully leveraged without the appropriate control plane functionality put in place.

ORCA extends the SDR control plane with a diverse set of configuration, parametrization and monitoring functionalities that can be run and controlled at different levels of the protocol stack and on different resources of the SDR computational architecture. The offered functionalities include parametrization interfaces of well-established RAT standards, runtime configuration of PHY/MAC schemes in the same radio hardware resource, advanced monitoring tools for increased context-awareness, and physical resource slicing allocation and coordination mechanisms.

Advanced reconfigurability is one of the first capabilities of ORCA which makes the end users/experimenters able to accelerate the evaluation procedure through runtime software/hardware update over the air.
