Modern High Level Synthesis (HLS) tools succeed well in their engineering productivity goal, but still require toolset and target technology specific modifications to the source code to guide the process towards an efficient implementation. Furthermore, their end result is a fixed function accelerator with limited field and runtime...

In the domain of big data analytics, the bottleneck of converting storage-focused file formats to in-memory data structures has shifted from the bandwidth of storage to the performance of decoding and decompression software. Two widely used formats for big data storage and in-memory data are Apache Parquet and Apache Arrow, respectively. In...

Many applications make extensive use of various forms of compression techniques for storing and communicating data. As decompression is highly regular and repetitive, it is a suitable candidate for acceleration. Examples are offloading (de)compression to a dedicated circuit on a heterogeneous System-on-Chip, or attaching FPGAs or ASICs...

The big data revolution has ushered an era with ever increasing volumes and complexity of data requiring ever faster computational analysis. During this very same era, CPU performance growth has been stagnating, pushing the industry to either scale their computation horizontally using multiple nodes in datacenters, or to scale vertically using...

We propose a novel reconfigurable hardware architecture to implement Monte Carlo based simulation of physical dose accumulation for intensity-modulated adaptive radiotherapy. The long term goal of our effort is to provide accurate dose calculation in real-time during patient treatment. This will allow wider adoption of personalised patient...

The proliferation of processing hardware alternatives allows developers to use various customized computing platforms to run their applications in an optimal way. However, porting application code on custom hardware requires a lot of development and porting effort. This paper describes a heterogeneous computational platform (the ALMARVI...

This paper presents and evaluates an approach to deploy image and video processing pipelines that are developed frame-oriented on a hardware platform that is stream-oriented, such as an FPGA. First, this calls for a specialized streaming memory hierarchy and accompanying software framework that transparently moves image segments between...

Embedded systems range from very simple devices, such as a digital watch, to highly complex systems such as smartphones. In these complex devices, an increasing number of applications need to be executed on a computing platform. Moreover, the number of applications (or programs) usually exceeds the number of processors found on such platforms....

Abstract—Multi-threaded applications execute their threads on different cores with their own local caches and need to share data among the threads. Shared caches are used to avoid lengthy and costly main memory accesses. The degree of cache sharing is a balance between reducing misses and increased hit latency.<br/>Dynamic caches have been...

Hoozemans, J.J. (author)
This thesis describes the design and implementation of an FPGA-based hardware platform based on the rVEX VLIW softcore and the adaption of a Linux 2.0 no_mmu kernel to run on that platform. The rVEX is a runtime reconfigurable VLIW softcore processor. It supports various configurations that allow programs to run faster or more efficient. The...
