Sigmastar Technology Assigned Two Patents

Data temporary storage apparatus, storage method and operation
Sigmastar Technology Ltd., Fujian, China, has been assigned a patent (11,436,017) developed by Lin, Bo, Zhu, Wei, and Li, Chao, Xiamen, China, for “data temporary storage apparatus, data temporary storage method and operation method.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A data temporary storage apparatus includes a moving unit coupled to a first storage unit and multiple second storage units. The moving unit receives a moving instruction having contents including a read address, a destination address and a predetermined moving rule. The moving unit further executes the moving instruction to fetch input data by row from the first storage unit according to the read address, and to temporarily stores one after another in an alternate and sequential manner the data in each row to each of the second storage units indicated by the destination address. The data moving, data reading and convolution approaches of the present invention implement in parallel data moving and a convolution operation, achieving a ping-pong operation of convolution units and enhancing convolution efficiency, while reducing memory costs since configuring two data storage spaces in a memory is not necessary.”

The patent application was filed on November 24, 2020 (17/103,036).

Control method for storage of driving recorder and storage control
Sigmastar Technology Ltd., Fujian, China, has been assigned a patent (11,435,922) developed by Lee, Chia-Jung, Chen, Fu-Cheng,and Lu, Chun-Nan, Zhubei, Taiwan, for “control method for storage device of driving recorder and storage device control system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A control method for a storage device of a driving recorder includes: configuring a directory entry of a storage device according to a predetermined directory entry stored in a storage unit, configuring a file allocation table of the storage device according to a predetermined file allocation table stored in the storage unit, and controlling a controller to write data to the storage device according to the directory entry and the file allocation table. In one embodiment, entries of the predetermined file allocation table are interleaved to accommodate multiple files and still support a continuous write operation.”

The patent application was filed on August 5, 2020 (16/985,288).
