Patent number: 10740673Abstract: A computer-implemented method is provided for refreshing cells in a Non-Volatile Memory (NVM)-based neuromorphic circuit wherein synapses are each composed of a respective cell pair formed from a respective Gp cell and a respective Gm cell of the cells. The method includes randomly selecting multiple neurons and reading a conductance of any of the synapses connected to the multiple neurons. The method further includes selecting any of the synapses connected to the selected multiple neurons for which the Gm conductance has reached a maximum conductance. The method also includes resetting the Gp cell and Gm cell of the selected synapses, and setting, at most, one of the Gp cell and Gm cell of each of the selected synapses to recover an effective total weight of each of the selected synapses.Type: GrantFiled: August 13, 2019Date of Patent: August 11, 2020Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Megumi Ito, Masatoshi Ishii, Atsuya Okazaki

Patent number: 9020376Abstract: An image forming apparatus capable of making image quality more stable than in the prior art. An electrostatic latent image is formed on the surface of a photosensitive member based on an image signal. A developing device develops the electrostatic latent image on the photosensitive member by toner to thereby form a patch image. An optical sensor detects the density of the patch image. A toner charge amount is calculated from the density detected by the optical sensor, and a change in the toner charge amount is predicted based on a plurality of results of the calculation of the toner charge amount. The image forming apparatus generates a ?LUT for use in correcting the relationship between the image signal and the density based on the predicted change in the toner charge amount.Type: GrantFiled: September 12, 2011Date of Patent: April 28, 2015Assignee: Canon Kabushiki KaishaInventors: Megumi Ito, Jun Hirabayashi

Patent number: 8990790Abstract: A method for executing native code in a distributed Java Virtual Machine (JVM) is disclosed herein. The method may include receiving, in a first thread executing in a remote execution container, a first native code-generated call, such as a Java Native Interface (JNI) call, to a second thread, the first call including a first array write request. The first call may be stored in an instruction cache and bundled with a second native code-generated call and sent to the second thread. The calls are unbundled and executed in the second thread. An opaque handle to an array returned by the second call is bundled with corresponding array data and returned to the first thread. The array data of the bundle is stored in a data cache and retrieved in response to requests for the array data addressed to the second thread. A corresponding computer program product is also disclosed.Type: GrantFiled: March 15, 2013Date of Patent: March 24, 2015Assignee: International Business Machines CorporationInventors: Michael Hilton Dawson, Xavier Rene Guerin, Megumi Ito, Graeme Johnson, Seetharami R Seelam

Patent number: 8943485Abstract: Detecting localizable native methods may include statically analyzing a native binary file of a native method. For each function call invoked in the native binary, it is checked whether resources accessed through the function call is locally available or not. If all resources accessed though the native method is locally available, the method is annotated as localizable.Type: GrantFiled: September 13, 2012Date of Patent: January 27, 2015Assignee: International Business Machines CorporationInventors: Michael H.
