The wordlength determination problem of linear time invariant systems with multiple outputs - a geometric programming approach

This paper proposes two new methods for optimizing objectives and constraints. The GP approach is very general and hardware resources in finite wordlength implementation of it allows us to solve optimally the relaxed wordlength multiple-output (MO) linear time invariant systems. The determination problem of MO LTI systems subject to a hardware complexity is measured by the exact internal prescribed output accuracy or bit budget (total wordlength). The wordlength used for each intermediate data. The first method hardware complexity is measured by the exact internal relaxes the wordlength from integer to real-value and formulates wordlength for each intermediate data and the output accuracy is the design problem as a geometric programming, from which an determined statistically by its output noise power resulting from optimal solution of the relaxed problem can be determined. The the rounding operations. Note that our approach can be regarded second method is based on a discrete optimiza...
