Abstract: Mechanisms are disclosed for performing efficient lossless encryption and decryption to reduce power consumption and improve the efficiency of processing streams of digital data. An input data stream associated with a stream of input data is received. A discrete wavelet transform is applied to a first serial input data value in the input data stream. Distributed components of the first serial input data value are distributed by computing a cumulative probability that the first serial input data value is less than or equal to a power-of-two range value associated with a power-of-two probability distribution function. An entropy encoded encryption value is computed based on a range variant asymmetrical numeral system based on the power-of-two probability distribution function. The entropy encoded encryption value is unloaded based on one or more computed next states. Compressed serial output data streams are compressed based on the unloaded entropy encoded encryption value.

Abstract: Techniques are described for designing and forming cells having transistor devices. In an example, an integrated circuit structure includes a plurality of cells where adjacent cells have a decreased distance between them along their height and a staggered via arrangement. Accordingly, a first cell may be adjacent to a second cell along a shared cell boundary. A first via is provided between a first gate structure of the first cell adjacent to the cell boundary and a first metal layer above the first gate structure, and a second via is provided between a second gate structure of the second cell adjacent to the cell boundary and a second metal layer above the second gate structure. No part of the first via is aligned with any part of the second via along the first direction.

Abstract: A computer server controls access to a hosted service using digital certificates that are requested from each client attempting to access the service. When a particular client accesses the hosted service, the host service requests a digital certificate from the particular client and issues a challenge message. The particular client signs the challenge message and provides a client digital certificate to the hosted service. The hosted service confirms that the signature on the challenge message matches the client digital certificate, and that the client digital certificate is signed by a trusted entity. Trusted entities are defined by an administrator by uploading, to the hosted service, one or more trusted digital certificates associated with a trusted entities. Using the trusted digital certificates, the hosted service confirms that the digital certificate provided by the particular client is signed by at least one of the trusted entities.

Abstract: A method, an apparatus, and a computer program product for inserting one or more global breakpoints for debugging computer software. A method, an apparatus, and a computer program product for removing one or more global breakpoints for debugging computer software. The inserting method includes the steps of: inserting a global breakpoint in a page containing software code if the page is present in memory; reading the page into memory if not present in memory, and inserting a global breakpoint in the page immediately after being read into memory; and detecting a private copy of the page if present, and inserting a global breakpoint in the private copy.
