title: What is the best way for interprocessor communication in Linux?
body: <p>I have two CPUs on the chip and they have a shared memory. This is not a SMP architecture. Just two CPUs on the chip with shared memory.</p>
  
  <p>There is a Unix-like operating system on the first CPU and there is a Linux operating system on the second CPU.</p>
  
  <p>The first CPU does some job and the result of this job is some data. After first CPU finishes its job it should say to another CPU that job is finished and the second CPU have to process this data.</p>
  
  <p>What is the way to handle interprocessor communication? What algorithm should I use to do that?</p>
  
  <p>Any reference to an article about it would be greatly appreciated.</p>
