Abstract
As microprocessor systems and single-chip microcomputers become more complex, so do the software systems developed for them. In many cases, software is being designed that incorporates multiple control functions running asynchronously on a single microprocessor. Here, discussion focuses on the motivation for running such multiple functions under the control of a real-time multitasking executive. A successfully implemented executive whose design is portable and suitable for use on most 8-bit microprocessors is presented.

Dataflow Mini-Graphs: Amplifying Superscalar Capacity and Bandwidth
MICRO 37: Proceedings of the 37th annual IEEE/ACM International Symposium on MicroarchitectureA mini-graph is a dataflow graph that has an arbitrary internal size and shape but the interface of a singleton instruction: two register inputs, one register output, a maximum of one memory operation, and a maximum of one (terminal) control transfer. ...
Mini-Threads: Increasing TLP on Small-Scale SMT Processors
HPCA '03: Proceedings of the 9th International Symposium on High-Performance Computer ArchitectureSeveral manufacturers have recently announced the first simultaneous-multithreaded processors, both as single CPUs and as components of multi-CPU chips. All are small scale, comprising only two to four thread contexts. A significant impediment to the ...
