3. The Big Picture The big picture. Talk about the levels of abstraction. Talk about the fact that this is where all programs get ushered into hardware execution. Circuits are increasing providing both opportunities (resources, bandwidth) and challenges (noise, power). Circuits are locally designed; software is globally intertwined Software is increasingly over designed for portability and productivity. The path between the two domains is increasingly stressed and inadequate due to this mismatch. The focus of the thrust is to provide a very strong path from the productivity oriented software domain into the performance oriented hardware domain. Translate device/circuit level innovations into visible benefit at the application/software level! The big picture. Talk about the levels of abstraction.
