Characterization of processing errors on analog fully-programmable cellular sensor-processor arrays

Research output: Chapter in Book/Report/Conference proceedingConference contribution


Analog processor arrays, particularly for vision chips, have been in development for a number of years. Based normally on the SIMD computing paradigm, they achieve very high instruction parallelism through use of compact processing elements. A fundamental aspect of processor operation is the ability to copy content of a register to another. This operation carries with it a number of errors. This paper identifies these errors and provides the means by which they can be separated and measured. These techniques can then be applied to analyze any operation upon an analog processor array. The results from such an analysis reflect on the susceptibility of the circuit to process mismatch, and thermal and switch noise performance of a particular analog memory design. ?? 2014 IEEE.
