Porting GCC to a Clustered VLIW Processor

A clustered architecture is a viable design choice when aiming to increase the performance of a VLIW processor while avoiding the hardware complexity and increased access times associated with a centralized register file. However, this places additional responsibility on the compiler: the production of an efficient cluster assignment. In this...

Dynamic loading and task migration for streaming applications on a composable system-on-chip

MPSoCs offer more and more processing capability to embedded systems. As a result, an increasing number of applications run on one system, sharing MPSoC resources. Some of these applications are streaming applications and may have real-time demands, e.g., guaranteed throughput, hence their temporal behavior has to be verified at design-time....

Improved static data-flow model for TDM scheduler

A streaming application like software defined radio (SDR) executed on a heterogeneous multi-processor system on chip (MPSoC) consists of various transceiver jobs that have to be scheduled on different processors concurrently. The hard real time performance requirements of these jobs can be guaranteed on the multi-processor system on chip (MPSoC)...

Tile-Based rasterization on an embedded Tile-based MPSoC

Graphics on a computer are often handled by a graphics pipeline. Rasterization is an important stage in this pipeline. It converts the basic elements of computer graphics, triangles, into the basic elements of a screen, pixels. This stage is very computation intensive and has a large memory footprint. The last decade a lot of research has been...

Task Scheduling Methods for Composable and Predictable MPSoC

Multiprocessor Systems on a Chip (MPSoCs) are suitable platforms for executing complex embedded applications. To reduce the cost of the hardware platform, applications share resources, which may result in inter-application timing interference due to resource request conflicts. Bounding or prohibiting this interference is crucial, as the timing...
