Abstract
An inter-processor data exchange system is provided in a multiple processor environment. The system includes a first message unit and a second message unit. The first message unit stores first data from a first processor and transfers the stored first data to the second message unit. The second message unit stores the first data from the first message unit and responsively provides the first data to a second processor. The second message unit also stores second data from the second processor and transfers the stored second data to the first message unit, and the first message unit stores the second data from the second message unit and responsively provides the second data to the first processor. Each message unit also provides an interrupt signal to the other processor for informing the other processor that the data is available for reading. In addition, each message unit provides a first flag signal for informing its own processor that the other processor has read the data.
