FPGA Software Architecture for Software Defined Radio

For working out the problem of waveform portability on the FPGA, this paper firstly comes up with the structural of platform abstraction layer on the FPGA, and then improves the standard message format of modem hardware abstraction layer. Lastly, this paper discusses the connection model which influences the resource consumption and the working efficiency about the platform abstraction layer, and compares the many-to-one connection model with the one-to-one connection model, draws a conclusion that one-to-one connection model is more suitable. Platform abstraction layer on the FPGA totally solves the problem of waveform portability, covering great significant in cutting down the cost of software defined radio system exploitation and improving the reconfigurability of the software defined radio system.
