Abstract :
This paper presents the implementation of several data coding functions used in Software Defined Radios, on R3TOS: a Reliable, Reconfigurable and Real-Time Operating System. The latter offers efficient high performance computing on FPGAs as well as protection against emerging faults, hence making it a perfect candidate for the implementation of SDRs. In particular, R3TOS´ ICAP-based Inter-task Communication Infrastructure (I2CI) has been used for data feeding and collection from coding functions, while a task context saving and restoration procedure, and a fast function parameterization system have been developed in order to improve system performance. The design of the data coding functions has been carried out using Xilinx´s rapid prototyping tool System Generator in order to ease their development.
