Abstract: In various embodiments a computer-implemented method for providing sustainability insights to a user designing an object. The method includes determining a value of a sustainability metric associated with a design of an object; determining a target value for the sustainability metric; determining an amount of progress made towards achieving the target value for the sustainability metric based on the value of the sustainability metric and the target value for the sustainability metric; and displaying, via a graphical user interface (GUI), a visual indication of the amount of progress made towards achieving the target value for the sustainability metric.

Abstract: In various embodiments a computer-implemented method for providing sustainability insights to a user designing an object. The method includes determining a first value of a sustainability metric associated with a design of an object, displaying, via a graphical user interface (GUI), a visual indication of the first value of the sustainability metric, and detecting a change to the design of the object. The method further includes, in response to detecting the change to the design of the object, determining a second value of the sustainability metric and displaying, via the GUI, a visual indication of the second value of the sustainability metric.

Abstract: A method for ciphering protected content communicated between a first device and a plurality of devices over a plurality of channels comprises performing authentication between the first device and each of the plurality of devices to create two or more shared key and initialization vector pairs allowing the ciphering of the protected content; generating a key stream for each of the channels based on a selected one of the two or more of shared key and initialization vector pairs; maintaining a buffer for each channel, each of the buffer containing the key stream generated for the corresponding channel; and ciphering data incoming on a selected channel using the selected key stream from the buffer corresponding to the selected channel.

Abstract: A system and method for communicating data between a first software and a second software located on first and second devices, respectively, has a hardware driver and memory associated with each device. Each communication of data from the first software to the second software allocates memory to manage data to be communicated from the first software to the second software, provides memory allocation information to the hardware driver associated with the first software, and transmits the data from the first hardware driver to the second hardware driver for delivery to the second software via the memory associated with the second software.

Abstract: There is disclosed a cache memory controller for storing cache data within a cache, the cache data comprising an unsecured version data to corresponding secured first data.

Abstract: A method for performing a cryptographic function on text to generate converted text comprises producing a random key stream having a first block size in a first frequency domain; converting the random key stream having a first block size in the first frequency domain to a random key stream in a second frequency domain; converting the random key stream having the first block size in the second frequency domain into smaller block sizes, thereby producing smaller block-sized random key stream of the second frequency domain; and converting the text using the smaller block-sized random key stream of the second frequency domain to produce the converted text. The frequency in the first frequency domain is preferably lower than the frequency in the second frequency domain.

Abstract: A system for caching is configured for a pending lock state of a cache line, pre-loading the cache line into cache memory, and locking the cache line to prevent eviction of the cache line from the cache memory. The cache line is associated with instructions or data, and the pre-loading of the cache line may include loading the cache line into the cache memory before an algorithm relying on the instructions or data needs them. The pre-loading of a cache line associated with instructions may be done without execution of the instructions. The pending lock state of the cache line may be achieved by configuring the cache system to know that, when a cache line associated with an address is loaded into the cache memory, it should lock the cache line. The locking of the cache line may be done by promoting the pending lock state to a locked state.

Abstract: A system for generating random key stream cipher texts passes an unencrypted random key stream through an AES engine to produce encrypted cipher text having a first block size in a first frequency domain; converts the encrypted cipher text in the first frequency domain to encrypted cipher text in a second frequency domain; and converts the encrypted cipher text having the first block size in the second frequency domain into smaller block sizes. The frequency in the first frequency domain is preferably lower than the frequency in the second frequency domain. The converting of the encrypted cipher text in the first frequency domain to encrypted cipher text in a second frequency domain may be effected by a dual clock domain FIFO.
