With the ongoing advancements in VLSI technology, the performance of an embedded system is determined to a large extend by the communication of data and instructions. This results in new methods for onand off-chip communication and caching schemes. In this paper, we use an arbitration scheme that exploits the characteristics of continuous ’media’ streams(More)
Turbo decoding offers outstanding error correcting capabilities, that will be used in wireless applications like the Universal Mobile Telecom Standard[4] (UMTS). However, the algorithm is very computational intensive, and therefore an implementation on a general purpose programmable DSP results in a power consumption which reduces the applicability of turbo(More)
With the ongoing advancements in VLSI technology, the performance of an embedded system is no longer determined primarily by the number and speed of functional units, but by the communication of data and instructions. This results not only in on-chip memory & caching schemes, but also in new methods for onand off-chip communication. In this paper, we(More)
After a analysis of the applications a common set of high-level functions is defined: RGB graphics blending, horizontal sample rate conversion, vertical sample rate conversion, noise reduction, 2D sharpness enhancement and video juggling. Different applications can be specified as different flowgraphs in which the nodes are the above functions. Figure(More)
High-end television requires a flexible architecture that supports the programmable display of multiple video windows. This was addressed in the TVP project. This article describes the signal flow graph concept as model for architecture and application and discusses the application requirements in terms of amount of compute power, memory size and memory(More)
