Open PhD position at Université Pierre et Marie Curie (UPMC) and LIP6 (Laboratoire d'Informatique de Paris 6), Paris

"Towards a unified code generator for libms and filters"

These thesis is part of a french Project ANR called "Metalibm" (Code generators for mathematical functions and filters). This project addresses the implementation of elementary functions (such as exponential or trigonometric, like those in the standard mathematical library - libm) and some signal processing functions. Performance and precision of these functions is of critical importance.

The combinatorial explosion of parameters to optimize in an implementation of a mathematical function or a signal processing filter makes manual implementation both tedious and sub-optimal in result. Code generation is hence the key for optimal implementations without huge development costs. Both communities, on the function and on the filter sides, have started investigating in code generators.

Several common approaches and subtasks exist in code generation for functions and for filters. First, in both cases, the generation chain goes through an approximation and an evaluation step. Second, both share techniques, such as variants of the Remez algorithm, problems, such as quantization and discretization, and similar code, like addition-and-multiplication sequences. However, existing early prototypes for function or filter code generator do not share any common formalism nor code. This is mainly due to the gap between both scientific communities. Additionally, from a practical standpoint, software prototypes for filter code generation are slightly less advanced in integration than software components for function generation.

This Ph.D. thesis is to bridge that gap, with a particular focus on the filter side. The Ph.D. candidate will investigate the state of the art on both sides, transferring know-how on code generation techniques and software from the function to the filter side. Several experiments on the applicability and stability of the resulting ad-hoc filter generation software will be conducted. These experiences also include work on optimal code generation for polynomial and FIR/ IIR filter evaluation, which is to be conducted jointly with the Université de Perpignan partner.

Based on the experiences with this ad-hoc filter generation code, the Ph.D. canditate will propose suitable formalism to express the commonalities in functioning of both function and filter code generation. This formalism, together with appropriate approaches, is supposed to yield a unified software tool-chain for optimized (and optimal) code generation for both signal processing filters and mathematical functions.
