Abstract: Described herein are photonic communication platforms that can overcome the memory bottleneck problem, thereby enabling scaling of memory capacity and bandwidth well beyond what is possible with conventional computing systems. Some embodiments provide photonic communication platforms that involve use of photonic modules. Each photonic module includes programmable photonic circuits for placing the module in optical communication with other modules based on the needs of a particular application. The architecture developed by the inventors relies on the use of common photomask sets (or at least one common photomask) to fabricate multiple photonic modules in a single wafer. Photonic modules in multiple wafers can be linked together into a communication platform using optical or electronic means.

Abstract: Systems and methods for performing signed matrix operations using a linear photonic processor are provided. The linear photonic processor is formed as an array of first amplitude modulators and second amplitude modulators, the first amplitude modulators configured to encode elements of a vector into first optical signals and the second amplitude modulators configured to encode a product between the vector elements and matrix elements into second optical signals. An apparatus may be used to implement a signed value of an output of the linear processor. The linear photonic processor may be configured to perform matrix-vector and/or matrix-matrix operations.

Abstract: A surgical instrument is disclosed comprising a control system and a strain gage circuit. The operation of the control system is modifiable by an input from the strain gage circuit.

Abstract: A computer (20) is configured for optimizing the processing rate of instructions and the throughput of data. The computer (20) includes a main memory (99), a memory control unit (22), a physical cache unit (100), and a central processor (156). A instruction processing unit (126) is included within the central processor (156). The function of the instruction processing unit (126) is to decode instructions and produce instruction execution commands or directing the execution of the instructions within the central processor (156). Instructions are transferred from the main memory (99) into a register (180) where the address fields of the instructions are decoded to produce a cracked instruction and these instructions are stored in a logical instruction cache (210). As the cracked instructions are selected they are transferred to an output buffer and decoder (214) where the remaining fields of the instructions are decoded to produce instruction execution commands.

Abstract: A vector processing computer is configured to operate in a pipelined fashion wherein each of the functional units is essentially independent and is designed to carry out its operational function in the fastest possible manner. Vector elements are transmitted from memory, either main memory, a physical cache unit or a logical cache through a source bus where the elements are alternately loaded into the vector processing units. The vector control unit decodes the vector instructions and generates the required control commands for operating the registers and logical units within the vector processing units. Thus, the vector processing units essentially work in parallel to double the processing rate. The resulting vectors are transmitted through a destination bus to either the physical cache unit, the main memory, the logical cache or to an input/output processor.
