This thesis presents the design of a Symmetric Multiprocessor (SMP) hybridthreads (hthreads) system that allows multiple threads to execute in parallel across multiple processors controlled by a single hardware scheduler. This approach increases the performance of software at a minimal cost to hardware. The issues that must be addressed for extending a uniprocessor kernel include system initialization, processor identification, context switching and concurrency control. As a proof of concept this thesis shows how hthreads, an existing hardware/software co-designed kernel can be extended to control multiple processors from a single, centralized hardware scheduler. Analysis results from executing on hardware reveal that for computationally intensive programs the typical speedup is in the range of 1.65x. This shows improvement in system performance while also illustrating issues associated with bus arbitration and memory access times.
