A new aggregated Hardware/Software (HW/SW) codesign approach to optimization of the digital signal processing techniques for enhanced imaging with real-world uncertain remote sensing (RS) data based on the concept of descriptive experiment design regularization (DEDR) is addressed. We consider the applications of the developed approach to typical(More)
In this paper, we address a new approach for high-resolution reconstruction and enhancement of remote sensing (RS) imagery in near-real computational time based on the aggregated hardware/software (HW/SW) co-design paradigm. The software design is aimed at the algorithmic-level decrease of the computational load of the large-scale RS image enhancement tasks(More)
In this paper, we propose a reconfigurable architecture of systolic array (SA) processors for near real time implementation of high-resolution reconstruction of remote sensing (RS) imagery. The proposed design is based on a Field Programmable Gate Array and performs the image enhancement/reconstruction tasks in an efficient reconfigurable processing(More)
Gaussian random numbers (GRN) generators are indispensable components in channel emulators for producing multiplicative and additive noises. Efficient designs of these GRN generators are required for testing the newest communications standards, which consider multiple channels working at higher data rates. In this paper, a new reconfigurable architecture(More)
A high-speed dual super-systolic core for reconstructive signal processing (SP) operations consists of a double parallel systolic array (SA) machine in which each processing element of the array is also conceptualized as another SA in a bit-level fashion. In this study, we addressed the design of a high-speed dual super-systolic array (SSA) core for the(More)
Developing computationally efficient processing techniques for massive volumes of hyperspectral data is critical for space-based Earth science and planetary exploration (see for example, (Plaza & Chang, 2008), (Henderson & Lewis, 1998) and the references therein). With the availability of remotely sensed data from different sensors of various platforms with(More)
