6678开发板 IPC例子

大家好,在论坛里下载了IPC例程IPC_example_on_6678,对ipc_interrupt.c里面的两个语句不是很理解,请教大家:

*(volatile uint32_t *) iIPCGRInfo[iNextCore] = interruptInfo;

  *(volatile uint32_t *) iIPCGRInfo[iNextCore] |= 1;

请问interruptInfo这个值赋予寄存器了吗?为什么我单步调试的时候寄存器的值没有发生变化呢?

*(volatile uint32_t *) iIPCGRInfo[iNextCore] |= 1;

又表示什么意思呢?谢谢大家
