In computing systems research, software tools (notably, simu-lators) provide low-cost, flexible, and low turn-around time facilities forinvestigations, but abstract away many hardware details. Hardware im-plementations onthe otherhand, providetheultimateproofsofconcept,butrequirehardwaredesignexpertise,areusuallyexpensiveand inflexi-ble,andarenotalwaysdesignedtoexposeallpossiblesystemparametersto researchers. They are also rarely the subject of active evolution overtimeasresearchplatformsintheirownright,assoftwaretoolsare.TheSunflowertoolsuiteisasuiteofhardwareplatformsandsimula-tion tools, intended to address these concerns. It comprises a full-system(embedded microarchitecture, networking, power, battery, device failureand analog signal modeling) simulator, a miniature energy-scavenginghardware platform, and a handheld computing device. The suite is in-tended to provide a set of complementary platforms for research inmicro- and system-architectures for embedded systems, with emphasesonenergy-efficiencyandfault-tolerance.Thistutorialwillprovidetheau-diencewithaworkingknowledgeofthedesign ...
