This paper presents the design and implementation of a thread virtual machine, called TNT (or TiNy-Threads) for the IBM Cyclops64 architecture (the latest Cyclops architecture that employs a unique multiprocessor-on-a-chip design with a very large number of hardware thread units and embedded memory) — as the cornerstone of the C64 system software. We highlight how to achieve high efficiency by mapping (and matching) the TNT thread model directly to the Cyclops ISA features assisted by a native TNT thread runtime library. Major results of our experimental study demonstrate good efficiency, scalability and usability of our TNT model/implementation.
