Studies on asynchronous communication ports for GALS systems

Abstract [en]

Digital systems generally use a global clock signal for the whole system. A System-on-Chip may have to communicate with the environment, using several different data rates that does not fit well to the single global clock frequency. When designing a digital system, it might be beneficial to divide the system into different clock domains where each domain can operate with its own clock frequency.

In this thesis, various clocking schemes are discussed. The synchronous clocking schemes that are discussed are mesochronous, plesiochronous, rational, oversampling and arbitrary clocking schemes.

The thesis focuses on the Globally Asynchronous Locally Synchronous scheme. This scheme transfers information between the different clock domains through dedicated communication channels. These communication channels use asynchronous handshaking protocols to transfer information without the necessity for a clock.

A communication channel consists of a transmitting and receiving port. Two types of communication ports are proposed in the thesis. The communication ports can be used either in a system with a static schedule or dynamic schedule of transactions. One of the ports can easily be implemented in different CMOS processes, since it only uses standard cells that can be found in most existing CMOS processes standard library.

A 2-dimensional Discrete Cosine Transform has been implemented using the GALS scheme and one of the proposed communication ports. The 2-D DCT has been implemented using a standard cell library supplied by AMS fora 0.35 µm CMOS process. A few improvements to the implementation are also discussed in the thesis.
