Abstract: Photon generating substrates for light-directed oligonucleotide synthesis are disclosed. Light is generated within a solid-state stack that supports growing oligonucleotides. The light may be generated by microLEDs, a pass-through liquid crystal panel, or an LCoS system. Light passes through a transmissive layer on which growing oligonucleotides are attached. Patterning of the light is controlled by selective activation of the microLEDs or by selective control of the transparency of a liquid crystal layer. Photolabile blocking groups are selectively removed by exposure to patterned light emitted from the photon generating substrate.

Abstract: Polymers synthesized by solid-phase synthesis are selectively released from a solid support by reversing the bias of spatially addressable electrodes. Change in the current and voltage direction at one or more of the spatially addressable electrodes changes the ionic environment which triggers cleavage of linkers that leads to release of the attached polymers. The spatially addressable electrodes may be implemented as CMOS inverters embedded in an integrated circuit (IC). The IC may contain an array of many thousands of spatially addressable electrodes. Control circuity may independently reverse the bias on any of the individual electrodes in the array. This provides fine-grained control of which polymers are released from the solid support. Examples of polymers that may be synthesized on this type of array include oligonucleotides and peptides.

Abstract: Disclosed is a facial recognition system/method, utilizing modules to perform the following routine: extracting a feature descriptor from a detected feature point of a detected face in an input image frame; and matching the extracted feature descriptor with at least one of a pre-stored facial image that is index-mapped, comprising at least a first and second round of matching, wherein the second round of matching only selects the index-mapped facial images that matched above a pre-defined threshold from the first round of matching. Optionally, the above described steps may be coupled to a Point-of-Recognition (POR) provisioning, enabling an on-demand gate-keeping and/or payment processing for an end-user at an event/venue entry or point-of-sale.

Abstract: A reach matrix scheduler circuit for scheduling instructions to be executed in a processor is disclosed. The scheduler circuit includes an N×R matrix wake-up circuit, where ‘N’ is the instruction window size of the scheduler circuit, and ‘R’ is the “reach” within the instruction window of the matrix wake-up circuit, with ‘R’ being less than ‘N’. A grant line associated with each instruction request entry in the N×R matrix wake-up circuit is coupled to ‘R’ other instruction entries among the ‘N’ instruction entries. When a producer instruction in an instruction request entry is ready for issuance, the grant line associated with the instruction request entry is activated so that any other instruction entries coupled to the grant line (i.e., within the “reach” of the instruction request entry) that consume the produced value generated by the producer instruction are “woken-up” and subsequently indicated as ready to be issued.

Abstract: Embodiments described herein are directed to a microarchitecture modeling tool configured to model and analyze a microarchitecture using a dependency graph. The dependency graph may be generated based on an execution trace of a program and a microarchitecture definition that specifies various features and/or characteristics of the microarchitecture on which the execution trace is based. The dependency graph includes vertices representing different microarchitectural events. The vertices are coupled via edges representing a particular dependency therebetween. The edges are associated with a cost for performing microarchitectural event(s) corresponding to the vertices coupled thereto. The dependency graph also takes into account various policies for structural hazards of the microarchitecture. The microarchitecture modeling tool analyzes the costs associated with each of the edges to determine a design metric of the microarchitecture.

Abstract: Performing speculative address translation in processor-based devices is disclosed herein. In one exemplary embodiment, a processor-based device provides a processing element (PE) that defines a speculative translation instruction such as an enqueue instruction for offloading operations to a peripheral device. The speculative translation instruction references a plurality of bytes including one or more virtual memory addresses. After receiving the speculative translation instruction, an instruction decode stage of an execution pipeline circuit of the PE transmits a request for address translation of the virtual memory address to a memory management unit (MMU) of the PE. The MMU then performs speculative address translation of the virtual memory address into a corresponding translated memory address.

Abstract: Systems and methods are disclosed for allocating resources to contexts in block-based processor architectures. In one example of the disclosed technology, a processor is configured to spatially allocate resources between multiple contexts being executed by the processor, including caches, functional units, and register files. In a second example of the disclosed technology, a processor is configured to temporally allocate resources between multiple contexts, for example, on a clock cycle basis, including caches, register files, and branch predictors. Each context is guaranteed access to its allocated resources to avoid starvation from contexts competing for resources of the processor. A results buffer can be used for folding larger instruction blocks into portions that can be mapped to smaller-sized instruction windows. The results buffer stores operand results that can be passed to subsequent portions of an instruction block.
