This paper presents a GPU based Range-Doppler radar imaging algorithm. It is implemented in OpenCL, which is deemed to be the industrial standard in the field of heterogeneous computing. Intensive floating-point calculations, for instance, large-scale FFTs, are effectively parallelized in this algorithm. The performance is promoted by orders of magnitude compared with CPU based implementation. It...
Open Computing Language (OpenCL) is a fundamental technology for cross-platform parallel programming. The emerging of OpenCL provides portable and efficient access to the power of modern processors. This revolutionary new technology is applied to accelerate the reconstruction of cone beam computed tomography (CBCT) on Graphics Processing Unit (GPU) in this paper. An OpenCL-based implementation of...
In this article we present a study on an implementation, named clAES, of the symmetric key cryptography algorithm Advanced Encryption Standard (AES) using the Open Computing Language (OpenCL) emerging standard. We will show a comparison of the results obtained benchmarking clAES on various multi/many core architectures. We will also introduce the basic concepts of AES and OpenCL in order to describe...
