Concise view

app1 is an asynchronous applicative activated each time a external interrupt arrives

At each period app21 reads the last Ethernet message from SimpleKeystonePlatform.MemorySubsystem.sram, makes some input treatments on the message, and makes it available for app1 in SimpleKeystonePlatform.ddr.

At each period app22 reads output data of app1 from SimpleKeystonePlatform.ddr. It transforms them into SimpleKeystonePlatform.spi frames. The frames are then store in SimpleKeystonePlatform.MemorySubsystem.sram. And finally app22 wakes up app3 by writing the address of the SimpleKeystonePlatform.spi frames into SimpleKeystonePlatform.dma_reg.

app4 is an asynchronous microcode running on the SimpleKeystonePlatform.eth component. Each time an SimpleKeystonePlatform.eth frame arrives, it transfers the payload of the frame to SimpleKeystonePlatform.MemorySubsystem.sram.
