This dissertation is primarily presenting the design of Digital Signal Processing (DSP) between the transmission in Bluetooth Low Energy Physical Layer (BLE PHY), and its implementation in a Field Programmable Gate Array (FPGA) device with Open Computing Language (OpenCL). During the design of DSP, it bases on the In-Phase/Quadrature-Phase (IQ) architecture to construct the modulation and demodulation processes of signal by utilizing a signal shaper scheme called Gaussian Frequency-Shift Keying (GFSK), in the short-rang communication it features strong anti-interference performance. Regarding with the OpenCL, it’s one of High-Level Synthesis (HLS) methods for FPGAs design. It not only features high productive, but also can realize high operational efficiency for FPGA by using parallel programming architecture. Moreover, here invokes a remote platform called Intel DevCloud to control the FPGA for verifying the program, it would make the design more convenient and economic.
