Publication number: 20230069030Abstract: An image processing device performs a filtering operation on image data according to a set of filter data, and includes a data reconstruction circuit, a memory and an intelligent processor. The data reconstruction circuit reconstructs data of blocks in the image data to generate first reconstruction data, and reconstructs the set of filter data to generate second reconstruction data. The memory stores the first reconstruction data and the second reconstruction data. The intelligent processor executes a depthwise convolution operation according to the first reconstruction data and the second reconstruction data to generate feature map data. Two adjacent of the multiple blocks have partially same data, and quantities of columns in the second reconstruction data are associated with a channel count of the depthwise convolution operation.Type: ApplicationFiled: June 6, 2022Publication date: March 2, 2023Inventors: Hu HE, Mingyong SUN

Publication number: 20220091780Abstract: The disclosure provides an intelligent processing apparatus including a processor and a direct memory access (DMA) controller. The processor generates a read command to read data from a memory. An address generation circuit generates multiple first address signals to the memory. A data processing circuit receives data that the memory outputs in response to the multiple first address signals, and performs a data interception process on the data received from the memory according to the read command and a first configuration parameter. A data port transmits the data processed by the data processing circuit to the processor. The multiple first address signals include multiple non-consecutive address signals such that the data read from the memory and processed by the data processing circuit corresponds to n-dimensional data blocks, where n is a positive integer greater than 1.Type: ApplicationFiled: August 4, 2021Publication date: March 24, 2022Inventors: Jianzhi WANG, Wei ZHU, Bingjie HE, Bo LIN, Mingyong SUN

Patent number: 9670115Abstract: A two catalyst system is described having separate catalyst beds for the selective conversion of acetylene to ethylene which reduces the concentration of acetylene, dienes, O2, and NOx is disclosed. An ethylene containing gas stream, such as an off-gas stream from a refinery catalytic cracking unit used in the production of fuels and gas oils, is treated by first contacting the gas stream with a silver catalyst supported on a metal oxide and subsequently contacting the gas stream with a ruthenium catalyst supported on metal oxide. The two catalysts are contained within contiguous continuous reactors or reactor compartments.Type: GrantFiled: February 15, 2012Date of Patent: June 6, 2017Assignee: Clariant CorporationInventors: Mingyong Sun, Steven A.

Patent number: 8426660Abstract: A method for purification of ethylene-containing feedstreams from steam crackers or fluid catalytic crackers (FCC), wherein the feedstreams further comprises hydrogen, carbon monoxide, acetylenes, oxygen, nitric oxides, is disclosed. The method comprises contacting an ethylene-comprising gas stream with a Ru-based catalyst at reaction temperatures of at least 120°C. The process results in an ethylene-containing feedstream wherein the ethylene is essentially free of acetylenes, nitric oxides and oxygen. The purifying of the feedstream occurs with minimal loss of ethylene.Type: GrantFiled: August 21, 2008Date of Patent: April 23, 2013Assignee: Sud-Chemie Inc.Inventors: Mingyong Sun, Martin Byran, Steven A.
