FPGA based LED illumination Control System
The resource utilization can be improved by the dynamic reconfiguration technique based on FPGA. The methods and prociples for dynamic reconfiguration is discussed in this article. Here, Xilinx Virtex-ⅡFPGA and SMCS Ethernet PHY (Physical Layer Transceiver) is utilised to implement a remote dynamic reconfiguration scheme. The RFDRS (Remote FPGA Dynamic Reconfiguration System) can remotely control the changes freely in the eight LED (Light emitting diodes) lighting modes. This method can be very much useful in the system upgrade and software update methods and also the resource utilisation of the Fpga is improved significantly. The chips are designed for super scales and high logic density in order to fulfill the requirements of complex functions of digital logic system. Many logic function modules are kept together to form a large scale digital system. But all the logic modules is notactive all the time, but they work round in time according to the requirement of the external utilisation. The Dynamic reconfigurable systems decompose the digital logic system. Keeping the logic functions the same as the normal, the resource utilization and the cost of the system is reduced significantly by configuring the logic dynamically. Hardware platform of MicroBlaze is developed via precisely performing MHS (Microprocessor Hardware Specification) and MPD (Microprocessor Peripheral Definition). Depending on these, the embedded processor and the IP core is customised. Managing the cutoff signal and setting the external memorizer and the peripheral address space is also done based on the MHS and the MPD.
