摘要： A data processing system including a processor operable in a plurality of modes and in either a secure domain or a non-secure domain. The system includes at least one secure mode being a mode in the secure domain, at least one non-secure mode being a mode in the non-secure domain, and a monitor mode. 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. Switching between the secure and non-secure modes takes place via the monitor mode and the processor is operable at least partially in the monitor mode to execute a monitor program managing switching between the secure and non-secure modes.

摘要： In a system supporting more than one operating system, a data processing thread executing on a first operating system may be subject to an interrupt which triggers interrupt handling on a second operating system. When that interrupt handling is completed on the second operating system, the first operating system is resumed using a return interrupt. The return interrupt specifies the data processing thread which is active on the second operating system such that an appropriate task switch or resumption may be made on the first operating system. The technique is particularly well suited to systems utilising a secure operating system and a non-secure operating system executing on the same hardware.

摘要： A processor may utilise two operating systems (Non-Secure, Secure) between which calls may be made. In order that a second operating system can track task switches made by a first operating system, each time a call is made to the second operating system, this call includes an identifier to enable discrimination between the task which was executing on the first operating system when that call was made. The identifier can be a call identifier and/or a target thread identifier and may include further parameters.

摘要： A data processing system includes a processor that can operate in a plurality of modes and in either a secure domain or a non-secure domain. At least one secure mode is a mode in the secure domain, and at least one non-secure mode is a mode in the non-secure domain. When the processor is executing a program in a secure mode and that program has access to secure data which is not accessible when the processor is operating in a non-secure mode, the processor is responsive to exception conditions for triggering exception processing. Specifically, the processor is responsive to a parameter specifying which of the exceptions should be handled by a secure mode exception handler executing in a secure mode and which should be handled by an exception handler executing in a mode within a current one of the secure domain and the non-secure domain when that exception occurs.

摘要： A data processing apparatus is operable in a plurality of modes and in either a secure domain or a non-secure domain. When operating in a secure mode within the secure domain a program has access to secure data which is not accessible when the processor is operating in a non-secure mode. A vectored interrupt controller is provided to generate an exception handler address in response to an occurrence of an except condition. The vectored interrupt controller is programmable with parameters specifying for each exception condition whether an exception handler in the secure or the non-secure domain should be triggered and an exception handler address for use if the exception occurs when in the appropriate domain. The vectored interrupt controller also includes a parameter specifying a domain switching exception handler address for use if the exception condition occurs when the processor is not in the appropriate domain.
