Patent number: 8086829Abstract: A method of processing data comprising: processing a function using a processor operable to perform a plurality of functions, the processor having interrupts enabled; receiving an interrupt at the processor; suspending processing of the function; accessing at least one control parameter, the at least one control parameter indicating whether processing of the function should be resumed from the point where it was interrupted or whether the function should be repeated following the interrupt; following completion of the interrupt continuing processing of the function either at a start of the function or at a point at which it was interrupted dependent upon the control parameter. A function being an application, a thread, a system software routine, or multiple processing steps defined by software.Type: GrantFiled: March 5, 2009Date of Patent: December 27, 2011Assignee: ARM LimitedInventors: Luc Orion, David Hennah Mansell, Michael Robert Nonweiler

Patent number: 7448050Abstract: In a data processing system using multiple operating systems, an interrupt which itself may be interrupted by a subsequent interrupt which will be serviced in a different operating system, guards itself against being overlooked when that subsequent interrupt has been handled by starting a stub interrupt handling routine in that other operating system before executing the main handling routine in the originating operating system. Thus, the stub interrupt handling routine will be recognised in the other operating system irrespective of other interrupt events which may occur and accordingly the interrupted interrupt handling may be restarted.Type: GrantFiled: November 17, 2003Date of Patent: November 4, 2008Assignee: ARM LimitedInventors: Simon Charles Watt, Christopher Bentley Dornan, Luc Orion, Nicolas Chaussade, Lionel Belnet, Stephane Eric Sebastien Brochier, Michael Robert Nonweiler, Dominic Hugo Symes

Patent number: 7171539Abstract: The present invention provides a data processing apparatus and method for controlling access to a memory in the data processing apparatus. The apparatus comprises a processor operable in a plurality of modes and a plurality of domains, said plurality of domains comprising a secure domain and a non-secure domain, said plurality of modes including at least one non-secure mode being a mode in the non-secure domain and at least one secure mode being a mode in the secure domain. The processor is operable such that when executing a program in a secure mode the program has access to secure data which is not accessible when the processor is operating in a non-secure mode. A memory is operable to store data required by the processor and comprises secure memory for storing secure data and non-secure memory for storing non-secure data, the processor being operable to issue a memory access request when access to an item of data in the memory is required.Type: GrantFiled: November 17, 2003Date of Patent: January 30, 2007Assignee: ARM LimitedInventors: David Hennah Mansell, Michael Robert Nonweiler, Peter Guy Middleton

Patent number: 7124274Abstract: An apparatus for processing data, the apparatus comprising: a processor operable in a plurality of modes and either a secure domain or a non-secure domain including at least one secure mode being a mode in the secure domain; and at least one non-secure mode being a mode in the non-secure domain. When the processor is executing a program in a secure mode, the program has access to secure data which is not accessible when the processor is operating in a non-secure mode. The processor further includes a non-secure translation table base address register and a secure translation table base address register operable in the non-secure and secure domain, respectively, to indicate a region of memory storing either non-secure or secure domain memory mapping data defining how virtual addresses are translated to physical addresses within either the non-secure or secure domain.Type: GrantFiled: November 17, 2003Date of Patent: October 17, 2006Assignee: Arm LimitedInventors: Simon Charles Watt, Christopher Bentley Dornan, Luc Orion, Nicolas Chaussade, Lionel Belnet, Stephane Eric Sebastien Brochier, David Hennah Mansell, Michael Robert Nonweiler
