Implementing a Real-time Synthetic Aperture Radar (SAR) Algorithm on TI’s C6678 DSP Reference Design
TIDEP0045
Overview
This reference design shows a real-time synthetic aperture radar (SAR) running on a multicore TMS320C6678 digital signal processor (DSP). One of the main challenges of SAR is to generate high-resolution images in real-time, since forming the image involves computationally-demanding signal processing procedures. We have implemented a SAR algorithm on the C6678 eight-core fixed- and floating-point DSP to show the full application performance and how it scales across one, two, four and eight DSP cores. Here, the range-Doppler SAR processing algorithm is modularized from a functional perspective and the computational task is mapped to multiple cores running in parallel. The task-mapping procedure is accomplished using OpenMP.
Features
- This reference design is tested and includes an evaluation module (EVM), software and a user guide.
- The hardware platform includes TMDSEVM6678 EVM for a high performance, cost-efficient development platform, using TMS320C6678 high-performance DSP based on our C66x KeyStone™ architecture.
- This design includes schematics, design files, and a bill of materials.
- SAR algorithm, input binary files and display scripts are included along with links to download BIOS-MCSDK and SDK software framework.
- The design guide discusses the Range-Doppler Algorithm implementation, required hardware and software and step-by-step guide to buliding and running the SAR application.
