Systems and methods for fast layered decoding for low-density parity-check (LDPC) codes
According to certain embodiments, a method is provided for fast layered decoding for Low-density Parity-Check (LDPC) codes with a Parity-Check Matrix (PCM) that includes at least a first layer and a second layer. The method includes reading, from a memory, Variable Node (VN) soft information, wherein the VN soft information is associated with a message from a VN to a Check Node (CN) of the second layer of the PCM. A new CN to VN message is calculated from the CN of the second layer of the PCM. New VN soft information is calculated for the VN. The new VN soft information is calculated based on the VN soft information and a new CN to VN message from a CN of the first layer to the VN and an old CN to VN message from the CN of the first layer to the VN such that the updating of new VN soft information is delayed by at least one layer. The fast layered decoding has lower decoding latency and utilizes the decoding hardware more efficiently than standard layered decoding techniques. This may be achieved by keeping the memory access and processing hardware units active simultaneously to avoid excess decoding latency. More specifically, certain embodiments may carry out memory access and computation process simultaneously, without any effort to make the row layers mutually orthogonal to each other. Another technical advantage may be that the proposed decoding algorithm adjusts the LLRs to partially account for deviations from the layered decoding due to non-orthogonal rows. |

Systems for generating instances of variable fonts
In implementations of systems for generating instances of variable fonts, a computing device implements a similarity system to receive input data describing attribute values of glyphs of an input font. The similarity system generates a custom instance of a variable font by modifying a value of a registered design axis of the variable font based on the attribute values. A similarity score is determined that describes a visual similarity between the custom instance of the variable font and the input font. The similarity system identifies an additional design axis of the variable font based on the similarity score and generates an instance of the variable font that is visually similar to the input font by modifying a value of the additional design axis. |

Methods and apparatus for dynamic data access provisioning
According to one aspect of this disclosure, dynamic access provisioning provides a centralized, flexible and consistent mechanism to grant access rights to data in real-time by dynamically evaluating access policies that involve user, data and environmental attributes. The mechanism handles complex authorization policies involving numerous different user types with differing access needs and rights, as well as numerous different data sources with differing access requirements. The mechanism also simplifies data usage by providing a single-context experience in a user session, giving access to data from multiple diverse data sources in one access context. Data could be in different domains or project spaces. Users (or the data access apps they create in the session) are not required to switch access contexts to access all the data they are entitled to. The system is also scalable, in that additional data users and data producers may be easily added to the dynamic access provisioning environment. |
