Implementation of Microblaze on ZYNQ FPGA using Wi-Fi for Controlling LED Matrix

Abstract

In many automotive applications LEDs provide a huge range of applications in turn signals,
smart cabinet lighting, head lights and also break lights. LED technology is extensively used in almost all
automotive lighting. For such automotive applications, an efficient controller or a soft-core microprocessor
like Microblaze which is implemented on a Xilinx Field Programmable Gate Arrays (FPGAs) can be used.
Microblaze is a 32-bit RISC processor which can be developed for embedded and real time applications and
is highly configurable. With the MicroBlaze processor a higher-performance processor preset can be
configured and can change the configuration parameters of the processor. In this paper, we implementation a
MicroBlaze processor integrated by MyRIO and control the LEDs through a Wi-Fi designed with
LabVIEW. This Wi-Fi enabled FPGA allows for fast and easy integration into remote embedded
applications. NI Lab-VIEW FPGA targets SoC technology and provides reconfigurable systems with
onboard processing to solve complex control. MyRIO consists of Zynq-7000 SoC dual cored with ARM
Cortex-A9 CPU. MicroBlaze IP core is an external IP and is incorporated into LabVIEW FPGA by
Component-Level intellectual Property (CLIP) module. The CLIP module is tuned to Xilinx FPGA which is
a structure used for implementing external FPGA IP into LabVIEW. Importing external IP’s helps to get
high performance and also reuse the code. The signal is received from a TiWi-BLE module which includes a
WLAN 802.11 b/g/n transceiver module. The module works on 2.4 GHz. It has a Bluetooth 2.1+EDR, Low
Energy and cost effective. Hence by switching to LED lightning system the energy can be reduced by almost
50% compared to the traditional incandescent lights. Thus reducing the electricity consumption can reduce
the carbon emissions. In addition, LED systems can provide compact, attractive and also helps to boost
safety
