Abstract
Zusammenfassung:<p>This book describes a specification, microarchitecture, VHDL implementation and evaluation of a SPARC v8 CPU with fine-grain multi-threading, called micro-threading. The CPU, named UTLEON3, is an alternative platform for exploring CPU multi-threading that is compatible with the industry-standard GRLIB package. The processor microarchitecture was designed to map in an efficient way the data-flow scheme on a classical von Neumann pipelined processing used in common processors, while retaining full binary compatibility with existing legacy programs. </p><ul><li>Describes and documents a working SPARC v8, with fine-grain multithreading and fast context switch;</li><li>Provides VHDL sources for the described processor;</li><li>Describes a latency-tolerant framework for coupling hardware accelerators to microthreaded processor pipelines;</li><li>Includes programming by example in the micro-threaded assembly language.</li></ul><p> </p><p> </p>
