![]() ![]() Using single-precision floating-point arithmetic. ![]() NVIDIA Tesla C1060 GPU and CUDA were selected as a suitable GPGPU platform for the implementation A single receiver-element, coherent pulse-Doppler system withĪ two-dimensional data storage model was assumed, due to widespread use and the interesting challengesĪnd opportunities that it provides for parallel implementation on the GPU architecture. GPUs with GPGPU capabilities for the computationally demanding software-defined pulse-Doppler The aim of this research is to address and characterize the challenges and intricacies of using modern Granularities within an optimization space that is considered non-linear in many respects. Explicit control is also granted over a deep memory hierarchy and parallelism at various The massive performance potential through a conventionally unfamiliar stream-programming However, numerous factors have to be considered in order to realize GPU architecture is well-suited for intrinsically parallel applications that require high dynamic range, Pipelines, high memory bandwidths of up to hundreds of Gigabytes per second and high floatingpointĬomputational performance of up to several Teraflops on a single chip. On the GPU (GPGPU) for high-performance computing applications through fully programmable Modern many-core GPUs provide general-purpose computation Provides a range of demanding and interesting computational challenges, and that present ample opportunitiesįor parallel processing. The first stage generally requires FIRįilters, correlation, Fourier transforms, and matrix-vector algebra on multi-dimensional data, which Data-independent processing is performed as the first stage and requires the highestĭata and computational rates of between 1 Gigaops to 1 Teraops, traditionally reserved for specializedĬircuits that typically employ restrictive fixed-point arithmetic. Processors that necessitate high data rates, computationally intensive processing, and strict latency Modern pulse-Doppler radars use digital receivers with high speed ADCs and sophisticated radar signal ![]()
