interprocessor communication in a multiprocessor system

Hello,

I am developing a multiprocessor project to compress the image. My proposed task is:

I have designed two processor sytem on de2-70.Now I want each processor to compress half part( half horizontal slice) from the image simultaneously.

I have tested the apllication for single processor image compression(png to jpeg image conversion)

Can you please provide any suggestion regarding above task? I want to how to achieve interprocessor communication?
