摘要
High data rate in nuclear spectroscopy can be achieved by using digital shaping techniques, Currently, the use of field-programmable gate arrays as digital processors is hugely increasing, especially in real time applications. In this paper, we deal with the problem of the minimization of the computation burden, in order to allow the use of the least possible hardware, which in turn allows the minimization of power dissipation, size etc, of the processing machine. In order to get at-most advantages of spatial computing in programmable devices, data-path structures of temporal computing process techniques have been revised, Among the improvements consequent to the optimization of architectures, we address three topics: reduction of processing speed, resource saving, and adaptive dynamic management of digital filters length for increasing resolution.
