A data processing system includes, in one embodiment, at least a first processor and a second processor and an interrupt controller, and the system provides a deferred inter-processor interrupt (IPI) that can be used to wake up the second processor from a low power sleep state. The deferred...
The first restriction on processor access is one of the following two types: (i) disabling the interrupts on a given processor; and/or (ii) sending inter-processor interrupts with synchronous waiting from one processor to another (including itself).Srivatsa S. Bhat...
That simple. For waiting/signaling you can use instructions like MWAIT or IPIs (inter-processor interrupts). Translate 0 Kudos Copy link Reply Community support is provided Monday to Friday.

In addition to the 16 IPC channels, PSoC 6 also provides 16 IPC interrupts. Each IPC interrupt can be used as event triggers from one core to another. This mechanism can be used in conjunction with an IPC channel to set up a messaging scheme with a notification event and acknowledgement....
软中断(software generated interrupts),用来多个核之间的通信(inter-processor communication)。软件通过写SGI寄存器来产生。 软件写ICC_SGI1R_EL1产生对应当前secure状态的group1软中断 软件写ICC_ASGI1R_EL1产生secure状态的group1软中断 软件写ICC_SGI0R_EL1产生secure状态的group0软中断 软件写SGI寄存器后,...
I am using imx6 sabrelite board in which #Linux OS running on core0 and #RTOS on core2. My task is to establish inter-processor communication between two operating systems. My idea is to create shared memory section and allow read-write access using Software Generated Interrupts(SG...
