- Abstract:
-
This paper shows the architectural proposal for an Application Specific Integrated Circuit (ASIC) designed to perform image reconstruction in real time. The used reconstruction technique is called Normalized Sampled Finite Sinc Reconstructor (NSFSR), and has been implemented in software formerly. In this work we developed an ASIC that implement NSFSR as a dedicated static pipeline architecture in hardware optimized in performance. We model and simulate this architecture using VHDL hardware description language. Based on these results, we conclude that the proposed ASIC implements the NSFSR correctly and it is optimized if compared with a software implementation. Improvements should de done, but the results obtained up to now are very expressive and promising.
