  • Patent number: 12045591
    Abstract: A compiler transforms a high-level program into configuration data for a coarse-grained reconfigurable (CGR) data processor with an array of CGR units. The compiler includes a method that identifies a skip buffer in a dataflow graph, determines limitations associated with the array, and searches for a lowest cost implementation topology and stage depth. At least three topologies are considered, including a cascaded buffer topology, a hybrid buffer topology, and a striped buffer topology. The lowest cost implementation topology and stage depth are based on the size of the buffered data (usually, the size of a tensor), the depth of the skip buffer, and the array's limitations. The hybrid buffer topology includes multiple sections of parallel memory units. The data travels between memory units in one section to adjacent memory units in a next section without intervening reorder buffers.

  • Patent number: 12039270
    Abstract: Described herein are embodiments of a framework named decomposable variational autoencoder (DecVAE) to disentangle syntax and semantics by using total correlation penalties of Kullback-Leibler (KL) divergences. KL divergence term of the original VAE is decomposed such that the hidden variables generated may be separated in a clear-cut and interpretable way. Embodiments of DecVAE models are evaluated on various semantic similarity and syntactic similarity datasets. Experimental results show that embodiments of DecVAE models achieve state-of-the-art (SOTA) performance in disentanglement between syntactic and semantic representations.

    Abstract: A novel compiler is described. The compiler is able to view source code of the application in its entirety and can do so from the inside. Unlike other tools which examine the forensic data from an application crash after the fact, from the outside, the compiler of the present invention can provide novel data on function call stacks and function profiles during runtime. The application may be stopped immediately during runtime to prevent further or potential damage, but the forensic data that is collected is focused and can be used to show where vulnerabilities exists in the application and how they were exploited. Hashes are taken of function call stacks and used as unique identifiers or thumbprints which can be used to reduce the volume of forensic data that needs to be analyzed after an attack.

  • Patent number: 11435989
    Abstract: Reuse of a thread-local return data structure to prevent a return data structure from being allocated every time asynchronous functions return. The system returns thread operation from the asynchronous function back to the caller function in a manner that the return data structure can be reused for future asynchronous function returns within that same thread. To do so, the system first accesses data that was generated by the asynchronous function in response to the caller function placing the function call to the asynchronous function. To determine if reuse is appropriate, the system determines that the caller function will use the return data structure as populated only once. If so, the system populates the reusable thread-local return data structure and returns that data structure to the caller.
