Patent number: 11354251Abstract: A method of offloading a computing kernel from a host central processing unit (CPU) to a co-processor includes obtaining, by an application running on the host CPU, a virtual address of a packet in a user level queue of a general packet processing unit (GPPU) and initializing, by the application, the packet referenced by the virtual address using an application programming interface of a user level device driver (ULDD). The packet includes a plurality of handles corresponding to the computing kernel. The method further includes finalizing, by the ULDD, the packet by including a list of bootstrap translation addresses comprising a physical address and a virtual address for each of the plurality of handles and output by a kernel level device driver (KLDD) of an operating system running on the host CPU, and accessing, by the application using the virtual address, results obtained from the co-processor processing the computing kernel.Type: GrantFiled: April 1, 2021Date of Patent: June 7, 2022Assignees: STMICROELECTRONICS (GRENOBLE 2) SAS, TECHNOLOGICAL EDUCATIONAL INSTITUTE OF CRETEInventors: Antonio-Marcello Coppola, Georgios Kornaros, Miltos Grammatikakis

Patent number: 10970229Abstract: An apparatus includes a first processor to execute a user-level application to operate in a virtual address, and a co-processor to execute a computing kernel associated with user-level application elements to be performed on the co-processor. The computing kernel is to operate in the virtual address. A memory includes physical addresses, and a partition used to map the virtual address associated with the first processor and to map the virtual address associated with the co-processor. A packet processor manages communications between the first processor and the co-processor. The packet processor receives packets from the first processor, with the packets including memory addresses identifying code and data of the computing kernel. The packet processor stores the packets in a queue associated with the user-level application, and outputs the packets to the co-processor, such that the co-processor is enabled to execute the computing kernel.Type: GrantFiled: March 8, 2019Date of Patent: April 6, 2021Assignees: STMICROELECTRONICS (GRENOLBE 2) SAS, TECHNOLOGICAL EDUCATIONAL INSTITUTE OF CRETEInventors: Antonio-Marcello Coppola, Georgios Kornaros, Miltos Grammatikakis

Patent number: 9519596Abstract: A method for controlling access of a processor to a resource, wherein the processor has an instruction set including a virtualization extension, may include executing a resource access instruction by the processor using the virtualization extension, whereby the resource access instruction conveys a virtual address (VA) and a virtual machine identifier. The method may also include translating the virtual address to a physical address based on the virtual machine identifier, and looking-up an access control rule table using the physical address as a search key. Each entry of the rule table includes a virtual machine identifier. The method further includes controlling access to the resource based on the output of the rule table and a match between the virtual machine identifier returned by the table and the virtual machine identifier conveyed in the resource access instruction.Type: GrantFiled: February 24, 2015Date of Patent: December 13, 2016Assignees: STMICROELECTRONICS (GRENOBLE 2) SAS, TECHNOLOGICAL EDUCATIONAL INSTITUTE OF CRETEInventors: Antonio-Marcello Coppola, Georgios Kornaros, Miltos Grammatikakis
