Execution Trace Graph Based Multi-criteria Partitioning of Stream Programs

Marco Mattavelli, Endri Bezati, Simone Casale Brunet, Malgorzata Maria Michalska

One of the problems proven to be NP-hard in the field of many-core architectures is the partitioning of stream programs. In order to maximize the execution parallelism and obtain the maximal data throughput for a streaming application it is essential to fi ...

A joint typicality approach to compute-forward

Michael Christoph Gastpar, Sung Hoon Lim, Chen Feng

A general framework for analyzing linear codes with joint typicality encoders and decoders is presented. Using this approach, we provide a new perspective on the compute-forward framework. In particular, an achievable rate region for computing the weighted ...

Exploring MPEG HEVC decoder parallelism for the efficient porting onto many-core platforms

Marco Mattavelli, Claudio Paolo Alberti, Simone Casale Brunet, Damien Jack De Saint Jorre

MPEG High Efficient Video Coding (HEVC) is likely to emerge as the video coding standard for HD and Ultra-HD TV resolutions. The two elements that push HEVC beyond the previous standards are a higher compression efficiency of about a factor of two, and the ...

Characterizing communication behavior of dataflow programs using trace analysis

Marco Mattavelli, Simone Casale Brunet

This paper investigates the relationship between two ways of analyzing streaming systems: trace analysis for dataflow programs with firing, and network calculus for network flows. While the former focuses on the structure of the dataflow computation while ...

A Methodology For Optimizing Buffer Sizes Of Dynamic Dataflow Fpgas Implementations

Marco Mattavelli, Claudio Paolo Alberti, Ab Al Hadi Bin Ab Rahman, Simone Casale Brunet

Minimizing buffer sizes of dynamic dataflow implementations without introducing deadlocks or reducing the design performance is in general an important and useful design objective. Indeed, buffer sizes that are too small causing a system to deadlock during ...
