Abstract: Methods and systems for obfuscating computer program code are disclosed. In an embodiment, a method of generating obfuscated binary code from input source code for execution on a target processor comprises: generating a set of random obfuscation transform selections; and iteratively optimizing the obfuscation transform selections until a termination criterion is met. The obfuscation transformation selections may comprise indications of custom instructions which are executable on the co-processor in order to reduce side channel leakage.

Abstract: In some examples, a ventilator includes a pneumatic connection configured to receive supply gas; an inspiratory path configured to deliver conditioned gas to lungs of a patient; a valve pneumatically connected to the pneumatic connection and configured to allow flow of the supply gas to the inspiratory path when the valve is open and block flow of the supply gas to the inspiratory path when the valve is closed; a pressure sensor configured to measure a pressure of the supply gas at the pneumatic connection; and electronic control circuitry configured to control an opening and closing of the valve based on the measured pressure to produce a desired volume of conditioned gas in the inspiratory path.

Abstract: A method and System on Chip (SoC) for adapting a reconfigurable hardware for an application kernel at run time is provided. The method includes obtaining a plurality of Hyper-Operations corresponding to the application. A Hyper-Operation performs one or more of a plurality of MIMO functions of the application. The method further includes retrieving compute metadata and transport metadata corresponding to each Hyper-Operation. Compute metadata specifies functionality of a Hyper-Operation and transport metadata specifies data flow path of a Hyper-Operation. Thereafter, the method maps each Hyper-Operation to a corresponding set of tiles in the hardware. The set of tiles includes one or more tiles and a tile performs one or more of the plurality of MIMO functions of the application.

Abstract: A method and System on Chip (SoC) for adapting a runtime reconfigurable hardware to decode a video stream, wherein the video stream is of one of a plurality of video types is disclosed. The method includes determining a video type of the video stream and identifying at least one functional block of a set of functional blocks in the runtime reconfigurable hardware in response to determining the video type. A functional block of the set of functional blocks corresponds to a decoding sub function of the video type. Thereafter, the method configures the one or more functional block based on a plurality of configuration parameters of the video type. Further, the method decodes the video stream using the one or more functional blocks in response of configuring the one or more functional block.
