The design, implementation and comparison of Software-Defined Radio (SDR) based on GALS architectures were focused on. GALS port controllers, previously proposed for implementation in ASIC, have been redesigned for use in conventional FPGAs, eliminating the need for hard macros. A GALS architecture for SDR was proposed and validated, comprising a wrapper described in VHDL. In addition, some guidelines...
Contemporary digital systems must necessarily be based on the “System-on-Chip - SoC” concept. An interesting style for SoC design is the GALS (Globally Asynchronous, Locally Synchronous) paradigm, which can be used to implement circuits in FPGAs (Field Programmable Gate Array). Although these devices have the benefits of low-cost and short development time, there's a major drawback which is implementing...
This paper proposes a novel structure and realization scheme of digital noise monitoring system based on B/S (Browser/Service) architecture and floating-point DSP. A robust, high accurate, real-time system using floating-point DSP (TMS320C6713) chip as core processor to design a high precision IIR filter for frequency weighting and the high-performance C8051F120 single chip processor as data collection...
