Publication number: 20230342068Abstract: A system includes a multi-port random-access memory (RAM) configured to store an instruction table. The instruction table specifies a regular expression for application to a data stream. The system includes a regular expression engine configured to process the data stream based on the instruction table. The regular expression engine includes a decoder circuit configured to determine validity of active states output from the RAM, a plurality of active states memories operating concurrently, wherein each active states memory is configured to initiate a read from a different port of the RAM using an address formed of an active state output from the active states memory and a portion of the data stream, and switching circuitry configured to route the active states to the plurality of active states memories according, at least in part, to a load balancing technique and validity of the active states.Type: ApplicationFiled: April 26, 2022Publication date: October 26, 2023Applicant: Xilinx, Inc.Inventors: Sachin Kumawat, David K.

Patent number: 10990517Abstract: Examples described herein relate to efficient memory access. An example is a system includes a programmable device, and a memory. The programmable device is coupled to the host and receives the read/write requests and the addresses associated therewith. The programmable device interleaves the read/write requests across multiple communication channels based on a subset of bits within each address. The memory receives the read/write requests from the programmable device. The memory stores contents associated with the addresses for write requests and returns contents associated with the addresses for a read request to the programmable device. The programmable device returns the received contents to the host for processing.Type: GrantFiled: January 28, 2019Date of Patent: April 27, 2021Assignee: XILINX, INC.Inventors: Hare K. Verma, Jiayou Wang, Vincent Mirian

Patent number: 10870162Abstract: Disclosed are an adaptive control method and equipment of arc swing in narrow gap welding. The control equipment is composed of an infrared camera system, a computer image processing system, an arc swing parameter control system, a bent-conducting-rod-type swing arc torch and the like. The infrared camera system acquires, in an external triggering manner, an infrared image of welding area when an arc is deviated towards the left or the right side wall groove, extracts information about the width of the groove in real time after image processing by a computer, and calculates an arc swing angle target value. The arc swing parameter control system controls a motor drive mechanism to rotate a bent conducting rod, and drives the welding arc to conduct circular arc swing according to the swing angle target value, thereby realizing the adaptive control for the arc swing angle according to changes of the groove width.Type: GrantFiled: June 30, 2015Date of Patent: December 22, 2020Assignee: JIANGSU UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Jiayou Wang, Jie Zhu, Na Su, Maosen Yang, Wenhang Li
