Datapath Synthesis; 10.1 Introduction10.2 Custom Instruction SelectionCustomizable processors have been described as the next natural step in the evolution of the microprocessor business: a step in the life of a new technology where top performance alone is no longer sufficient to guarantee market success. Other factors become fundamental, such as time to market, convenience, energy efficiency, and ease of customization. This book is the first to explore comprehensively one of the most fundamental trends which emerged in the last decade: to treat processors not as rigid, fixed entities, which designers include "as is? in their products; but rather, to buMorgan Kaufmann series in systems on silicon.Embedded computer systemsEmbedded computer systemsDesignEmbedded computer systems.Embedded computer systemsDesign.621.392Ienne Paolo1147957Leupers Rainer1497130MiAaPQMiAaPQMiAaPQBOOK9910784651103321Customizable embedded processors3722176UNINA
