The Tile Processing Module is a board performing the data acquisition, channelisation and beamforming for 16 antennas in the SKA LoW Frequency Aperture Array instrument. 16 TPMs are connected using a 40 Gb Ethernet network, to compose a LFAA station with 256 antennas. The LFAA signal processing firmware is composed of modular elements, which are programmed using a standard memory mapped interface. Each module is managed by a software element (plugin), written in Python, which allows a higher level software to manage the board using a standardized set of functions. Here the interface for each module, and the associated plugin, is described for all modules used in the TPM signal processing chain.
