A Design Path for Design of GALS Based Communication Systems
The GALS (Globally Asynchronous Locally Synchronous) approach is highly suitable for implementation of communication systems. In this paper we describe an efficient design flow for GALS design based on commercial tools. As design example we have selected a digital FIR filter. It is a nontrivial task to develop an efficient design flow for GALS based systems because of the asynchronous parts. Bo...
متن کاملGlobally Asynchronous Locally Synchronous FPGA Architectures
Globally Asynchronous Locally Synchronous (GALS) Systems have provoked renewed interest over recent years as they have the potential to combine the benefits of asynchronous and synchronous design paradigms. It has been applied to ASICs, but not yet applied to FPGAs. In this paper we propose applying GALS techniques to FPGAs in order to overcome the limitation on timing imposed by slow routing.
متن کاملGALS Implementation of a 2-D DCT Processor
This paper describes an implementation of a 2-dimensional DCT processor and shows that the Globally Asynchronous Locally Synchronous (GALS) approach is highly suitable for implementation of such processors. Primarily the GALS approach increases the design efficiency by using the divide-and-conquer approach. Simulation results on the port controller are presented.
متن کاملEliminating Nondeterminism to Enable Chip-Level Test of Globally-Asynchronous Locally-Synchronous SoC’s
Globally asynchronous locally synchronous (GALS) clocking applied to a system-on-a-chip (SoC) results in a design in which each core is a synchronous block (SB) of logic whose locally generated clock has an independent frequency and phase. Data is exchanged between cores using an asynchronous communication protocol. The nondeterministic synchronization strategies used by most GALS architectures...
متن کاملTernary Tree Asynchronous Interconnect Network for Gals’ Soc
Interconnect fabric requires easy integration of computational block operating with unrelated clocks. This paper presents asynchronous interconnect with ternary tree asynchronous network for Globally Asynchronous Locally Synchronous (GALS) system-on-chip (SOC). Here architecture is proposed for interconnection with ternary tree asynchronous network where ratio of number NOC design unit and numb...
