Design of an FPGA-based Embedded System for a reliable loading of multichannel data in the on-chip memory for DSP purposes

The approach to perform Digital Signal Processing (DSP) by means of an Embedded System (ES) based on Field Programmable Gate Array (FPGA) and related Systems on Chip (SoC) is very common, useful and efficient in the electronic design practice. Moreover, one of the main problems to solve is to interface the ES with an external data source. The problem becomes further complicated for multichannel signals. To this aim, the author has designed an ES able to efficiently load into the FPGA memory data to be processed by the FPGA itself. Therefore, the aim of this paper is to describe the designed interface and its validation results. The design has been performed using the Cyclone V FPGA by Altera. The test has been performed using the evaluation board DE1-SoC by Terasic. The test bench has been developed in MATLAB environment.
