Abstract: A memory allocation device for deployment within a host server computer includes control circuitry, a first interface to a local processing unit disposed within the host computer and local operating memory disposed within the host computer, and a second interface to a remote computer. The control circuitry allocates a first portion of the local memory to a first process executed by the local processing unit and transmits, to the remote computer via the second interface, a request to allocate to a second process executed by the local processing unit a first portion of a remote memory disposed within the remote computer. The control circuitry further receives instructions via the first interface to store data at a memory address within the first portion of the remote memory and transmits those instructions to the remote computer via the second interface.

Abstract: Described are self-learning systems and methods for adaptive management of memory resources within a memory hierarchy. Memory allocations associated with different active functions are organized into blocks for placement in alternative levels in a memory hierarchy optimized for different metrics of e.g. cost and performance. A host processor monitors a performance metric of the active functions, such as the number of instructions per clock cycle, and reorganizes the function-specific blocks among the levels of the hierarchy. Over time, this process tends toward block organizations that improve the performance metric.

Abstract: A sensing device projects near-field spatial modulations onto a closely spaced photodetector array. Due to physical properties of the grating, the point-spread response distributes spatial modulations over a relatively large area on the array. The spatial modulations are captured by the array, and photographs and other image information can be extracted from the resultant data. An image-change detector incorporating such a sensing device uses very little power because only a small number of active pixels are required to cover a visual field.
