Symbolic Polyhedral-Based Energy Analysis for Nested Loop Programs
Avinash Mahesh Nirmala, Dominik Walter, Frank Hannig +1
This work presents a symbolic approach for estimating the energy consumption for nested loop programs when mapped and scheduled on parallel processor array accelerator architecture…
Loop Control Management in Tightly Coupled Processor Arrays (TCPAs)
Dominik Walter, Frank Hannig, Jürgen Teich
Multidimensional loop kernels often suffer from control overhead that can dominate execution time on parallel loop accelerators. Tightly Coupled Processor Arrays (TCPAs) offload lo…
Evaluation of CGRA Toolchains
Dominik Walter, Marita Halm, Daniel Seidel +4
Increasing demands for computing power also propel the need for energy-efficient SoC accelerator architectures. One class for such accelerators are so-called processor arrays, whic…
Mapping and Execution of Nested Loops on Processor Arrays: CGRAs vs. TCPAs
Dominik Walter, Marita Halm, Daniel Seidel +4
Increasing demands for computing power also propel the need for energy-efficient SoC accelerator architectures. One class of such accelerators are so-called processor arrays, which…
Symbolic Loop Compilation for Tightly Coupled Processor Arrays
Michael Witterauf, Dominik Walter, Frank Hannig +1
Loop compilation for Tightly Coupled Processor Arrays (TCPAs), a class of massively parallel loop accelerators, entails solving NP-hard problems, yet depends on the loop bounds and…
