The Square Kilometer Array (SKA) will be the biggest radio telescope in the world, with unprecedented sensitivity, angular resolution, and survey speed. Collectively, the antennas composing the SKA are expected to gather 14 exabytes and store one petabyte of data every day, requiring exa operations per second for the processing [19]. In this work, we focus on the implementation of the central signal processor (CSP) of the SKA1-Low, the SKA’s aperture array instrument that will be built in the first phase of the deployment of the SKA and consisting of 512 stations, each containing 256 dual-polarized antennas [19]. We refer in particular to a two-stage signal channelization implementation in which the signal-processing load is distributed between the stations and the CSP (see Figure 1 for details) [19]. This configuration is similar to the one implemented in LOFAR, the low-frequency aperture array built in the Netherlands [13].
