Today many applications require high-speed communications. To provide for the protocol processing with efficient hardware and software the use of a flexible and efficient platform becomes very import for the high-speed communications networks. In this paper we first describe a top-level view of the implementations platform for handling communication(More)
Retargetability allows an easy adoption of a simulator on different processor architectures without a time consuming redesign of all tools. This is evident for an efficient HW/SW codesign. In this paper we describe a tool set for fast and easy simulation of processor architectures based on a retargetable simulator core. This approach helps to reduce the(More)
The new FPGA-based GPS receiver under development as a joint project by UNSW and NICTA is described. The particular advantages of an FPGA receiver are highlighted, especially those that are consistent with the future research goals of the participants: signal processing algorithms, integration with other sensors and reconfigurability.
Realizations of demanding applications particularly in the field of mobile communications often require processing performance which is far beyond what is delivered by DSPs today. To avoid designing inflexible ASIC solutions a powerful, highly parallel DSP core for System-on-Chip domains is presented in this paper. Targeted for a wireless OFDM based modem(More)
The ongoing advances in semiconductor technology are the enabler for complete System on Chip (SoC) solutions. In this SoC domain Digital Signal Processors (DSPs) are employed to carry out software driven digital signal processing tasks. Although DSPs could still be modified in the SoC domain, they are mainly employed as fixed DSP cores. Possible adaptations(More)
In this article we present the concept of a FPGA-based GPS receiver architecture with the aim of providing a framework for investigating new receiver architectures for current and upcoming GNSS standards. This development system facilitates researchers to prove new receiver concepts using real signals, which nowadays can only be simulated using tools such(More)
Sensor networks allow monitoring, tracking, and controlling various aspects of the physical world. Any data retrieved or generated is only useful if considered in relation to its time and space coordinates. CSIRO's ICT Centre is currently developing a platform for distributed ad-hoc sensor networks. This paper describes the evaluation of various cooperative(More)
