Abstract
This thesis addresses aspects of support for programming models in Network-on-
Chip-based many-core architectures. The main focus is to consider architectural
support for a plethora of programming models in a single system. The
thesis has three main parts. The first part considers parallelization and scalability
in an image processing application with the aim of providing insight
into parallel programming issues. The second part proposes and presents the
tile-based Clupea many-core architecture, which has the objective of providing
configurable support for programming models to allow different programming
models to be supported by a single architecture. The architecture features a
specialized network interface processor which allows extensive configurability
of the memory system. Based on this architecture, a detailed implementation
of the cache coherent shared memory programming model is presented. The
third part considers modeling and evaluation of the Clupea architecture configured
for support for cache coherent shared memory. An analytical model
and the MC sim simulator, which provides detailed cycle-accurate simulation of
many-core architectures, have been developed for the evaluation of the Clupea
architecture. The evaluation shows that configurability causes a moderate increase
of the application execution time. Considering the improved flexibility,
this impact is considered acceptable as the architecture can potentially exploit
application-specific optimizations and offers a valuable platform for comparing
programming models.
