Abstract:
1. An electronic slave device to receive P-bit width symbols transmitted from an external master device X symbols being placed within a N-bit width dataword which is transmitted all at once from the master device to the slave device through a system bus, the slave device comprising: a writeable memory, a hardware data packing block comprising a configurable multiplexing unit having inputs connected to the system bus wires to receive in parallel each bit of the dataword, outputs connected to the respective data write pins of the memory to output in parallel each bit of a rearranged dataword to be recorded, and rearrangeable connections between the inputs and the outputs according to a set configuration, a format register for storing a transport format value, the value of which can be set by the external master device to at least two different values, and a logic circuit capable of setting the connections of the multiplexing unit according to the value of the format register to obtain a rearranged dataword having at least two symbols with at least one symbol with a shifted position by comparison to the position of this symbol in the received dataword, said rearranged dataword having a data occupation that is defined by said transport format value.
