Abstract: A computer implemented method for executing applications on a host system. The method includes identifying application execution code of an application and a set of application execution dependencies of the application. The method creates a basic run-time environment (BRE) for the application on the host system. The method maps a root file system of the host system into the BRE. The method copies the application execution code of the application to an application directory in the BRE. The method maps the resource files of the host system to the directories in the BRE for the set of application execution dependencies corresponding to the resource files. The method initiates execution of the application through the BRE using the resource files of the host system that are mapped to the set of application execution dependencies of the application in the BRE.

Abstract: A circuit includes a RC-CR circuit and a second circuit. The RC-CR circuit outputs a first signal at a first output node over a RC path, and a second signal at a second output node over a CR path. The second circuit is coupled to the RC-CR circuit at the first output node over the RC path. The second circuit includes an array of capacitors coupled in parallel and a plurality of switches, and each of the array of capacitors is connected, in series, to a corresponding switch in the plurality of switches. Each of the array of capacitors and its corresponding switch are coupled between the first output node and a ground. The plurality of switches is switched on or off such that the first signal and the second signal have a phase difference that falls within a predetermined phase range.
