“…The major advantage of using Eclipse is that it allows Linux application debugging as well. This way hardware and software parameters can be monitored in real time and system faults can be narrowed down to certain part of the software/hardware [11][12][13].…”

Recent trends suggest Global Navigation Satellite System (GNSS) receiver technology has tremendous scope for satellite applications such as precise orbit determination and reflectometry. Space borne receivers are characterised by low-power requirements, high processing speed and radiation resistant electronic components. Such sophisticated receivers, also called hardware GNSS receivers, are fabricated for specific applications and hence lack of design flexibility. On the other hand, a software GNSS receiver allows easy design modifications without any hardware component replacement. Software receivers employ reconfigurable hardware elements called field-programmable gate arrays (FPGAs). Hardware designs can be implemented or modified in FPGAs using Hardware Description Language (HDL). In this research, a low-power, low-cost software GNSS receiver has been designed and developed using a combination of a microprocessor and FPGA, i.e. System on Chip (SoC). The developed software GNSS receiver is capable of detecting GPS satellites, tracking these signals and computing receiver position estimates. Efficient task partitioning is achieved by implementing operations in both the FPGA and the microprocessor. Also demonstrated in the improvement of processing speed by 20% when certain GNSS receiver operations are performed in the FPGA instead of the microprocessor.

“…It looks at the operational performance as well as the power needed to implement the functionality of the design system. Salem, Othman & Saoud [12] implemented a real-time.The operating system on both hard-core and Soft-core processors and used them to control a DC engine car. In his paper, Prado [13] presented a comparison of the speed, power, flexibility and cost between a microprocessor and its soft-core version.…”

Actually multi-core processors designs are limited in power consumption and performance. Consequently, it is not possible to optimize further the performance without increasing power consumption. The main challenge in multi-core processors is the fact that they have heterogeneous hardware components. This article will study different technologies for implementing multi-core processors in FPGA devices. The minimum requirement to ensure low power consumption is parallelism. The purpose of this study is to highlight the latest methodologies used in terms of environment, clock signal, testing, flexibility, cost, availability and power consumption.
