Present day parallel computers often face the problems of large software overheads for process switching and inter-processor communication. These problems are addressed by the Multi-Threaded Architecture (MTA), a multiprocessor model designed for efficient parallel execution of both numerical and non-numerical programs. We begin with a conventional processor, and add the minimal external hardware necessary for efficient support of multithreaded programs. The article begins with the top-level architecture and the program execution model. The latter includes a description of activation frames and thread synchronization. This is followed by a detailed presentation of the processor. Major features of the MTA include the Register-Use Cache for exploiting temporal locality in multiple register set microprocessors, support for programs requiring non-determinism and speculation, and local function invocations which can utilize registers for parameter passing.ETX
