Multi-core chips present a new computing environment that can benefit from software support for non-numerical applications. Heterogeneous cores will allow efficient sophisticated multi-level parallel processing. Techniques are described that enable the association of the elements of related heterogeneous SIMD vectors. These techniques can be used for processing arrays of records, dynamic alloca...

The large data-transfer time among different cores is a big problem in heterogeneous multi-core processors. This paper presents a method to accelerate the data transfers exploiting data-transfer-units together with complex memory allocation. We used block matching, which is very common in image processing, to evaluate our technique. The proposed method reduces the data-transfer time by more tha...

As a result of the demand for high performance graphics capabilities driven by the computer video game industry, the processing performance of video cards is rapidly evolving. Recent trends in computing have shifted toward multi-core processors and programmable graphics processors equipped with highly parallel data paths for processing geometry and pixels. Multi-core machines are now readily av...

For flexible mapping of various task-level pipelines on a multi-core processor, the authors proposed the memory-centric network-on-chip (NoC). The memory-centric NoC manages producer–consumer data transactions between the tasks in the case of task-level pipelines are distributed over multiple processing cores. Since the memory-centric NoC manages the data transactions, it relieves burden of the...

Generic purpose multi-core PC architectures are facing performance challenges of high rate packet reception on gigabit per second and higher speed network interfaces. In order to assign a CPU core to a networking softIRQ, the single input queue design of the low-level packet processing subsystem relies on the kernel's Symmetric Multiprocessing (SMP) scheduler, which does not perform load balanc...

Multi-core CPU architectures have become prevalent in recent years. A number of multi-core CPUs consist of not only multiple processing cores, but multiple different types of processing cores, each with different capabilities and specialisations. These heterogeneous multi-core architectures (HMAs) can deliver exceptional performance; however, they are notoriously difficult to program effectivel...

Multithreading has been shown to be a powerful approach for boosting a system performance. One of the good examples of applications that benefits from multithreading is image processing. Image processing requires many resources and processing run time because the calculations are often done on a matrix of pixels. The programming language Java supports the multithreading programming as part of t...

Developing software for non SMP multi-core systems such as the 48 core Intel-SCC or the TI-TMS320C6678 is a complex task, and will become even harder with the emerging heterogeneous multi-core systems combining different architectures on a single chip. To tackle this issue, Altreonic has adopted a formalized approach to embedded systems development. Of particular interest is the formally develo...
