In Cortex-R4, the interrupt from which part to send to the core?
In the bellow diagram, Cortex-R4 doesn't give an interrupt input port, so I want ask the interrupt connect to the Cortex-R4 kernel from which part?
Hello,ARM has not released the single core Cortex-A7 TRM, although I am not sure such a part exits.Therefore I don't know the connection between each core and GIC.However, I believe it is the same as Cortex-R4.For your information, the blow is the picture from TI's document "Interrupt and Exception Handling on Hercules™ ARM® Cortex®-R4/5-Based Microcontrollers" http://www.ti.com/lit/an/spna218/spna218.pdf .
