The 4stack Processor uses stack based instructions for a four way VLIW processor. If implemented in state of the art technology, the 4stack processor would significantly outperform high-end DSPs like the TMS 320C6x or the TigerSHARC, and also allow to run the complete application on a single processor (no additional RISC core required).

Stack-like instructions with implicit addessing reduce memory bandwidth. Reduced memory bandwidth improve cache usage and speed up large programs.
Multiple stacks overcome the limited parallelism of single-stack machines. Using several stack-like organized register files instead of one huge multiported register file minimizes conflicts and greatly reduces gate count for these units.
Procedure calls are cheaper on stack machines, since register spills and fills are done automatically. This makes high level languages (especially object oriented) and modern OSes faster.
