Abstract

The SKA Pulsar Search requires a fast real time data processing in order to keep-up to the SKA pulsar data production. Such pipeline (named CSP-NIP-PSS pipeline) will be implemented as a collection of software modules running on PSS nodes or on the softwaree accelerators (GPU or FPGA) attached to them.

The FLDO is a software module within the CSP-NIP-PSS pipeline. The FLDO receives the SCL and FFB and produces the optimized candidates and their associated data. This component is responsible for producing the periodicity search data products that form the output of the CSP-NIP-PSS sub-element.

The present document presents two possible implementations on GPU and on FPGA accelerators.

The Pdf version of this report will be publicy available after SKA CDR (expected late 2018)
