  • Embedded system with interrupt handler for multiple operating systems
    Patent number: 7062766
    Abstract: A communication device includes one processor to run at least two operating systems simultaneously. The at least two operating systems include a first operating system for mobile station functions having a first group of threads, the mobile station functions including operations for communicating with another device, and a second operating system for data processing functions having a second group of threads, the data processing functions including operations for processing data internally in the communication device, where the operating systems communicate with each other. The communication device further includes at least one user interface, provides for generating an interrupt, provides for selecting a thread to execute as a result of the interrupt including a common interrupt handler for the at least two operating systems, and provides for transmitting interrupt data to the operating system from which the thread was selected, including the thread to execute.

  • Embedded system with interrupt handler for multiple operating systems
    Patent number: 6631394
    Abstract: An embedded system (1) comprising at least one processor (2) for running an operating system (OS_A, OS_B). The embedded system (1) further comprises: means (17, 401, 412) for running at least two operating systems (OS_A, OS_B) in said processor (2), a first operating system (OS_A) comprising a first group of threads (THA1, THA2, THA_IDLE), a second operating system (OS_B) comprising a second group of threads (THB1, THB2, THB_IDLE), means (nFIQ, nIRQ, SWI) for generating an interrupt (FIQ, IRQ, SWI) to said processor (2), means for examining (401, 603, 617) to the execution of which thread (THA1, THA2, THB1, THB2, THA_IDLE, THB_IDLE) the interrupt (FIQ, IRQ, SWI), that has come to the processor (2), affects, and means (401, 412, 603, 609, 617) for transmitting interrupt data to said operating system (OS_A, OS_B) which relates to the thread (THA1, THA2, THB1, THB2, THA_IDLE, THB_IDLE) affecting the interrupt (FIQ, IRQ, SWI) received by the processor (2).
