This paper presents a data communication interface specifically designed to sustain the predictable operation of hard real-time systems. The general interface architecture, data format and communication protocols are discussed, along with a case study - the full-duplex SPI (serial peripheral interface) for the HARETICK kernel. Some of the most interesting experimental results are also presented.
