This TI design shows a real-time synthetic aperture radar (SAR) implementation running on a TI's 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. TI has 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.
- This reference design is tested, and includes an evaluation module (EVM), software and a user's guide.
- The hardware platform includes TMDSEVM6678 EVM for a high performance, cost-efficient, standalone development platform, using theTMS320C6678 high-performance DSP based on TI's 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.
