An accumulator instruction set architecture is simpler than an instruction set of a (reduced instruction set computer) RISC architecture. Therefore, an accumulator instruction set that does within one instruction less than a typical RISC instruction is probably more “reduced” than a standard load/store register based RISC architecture.

This paper presents Leros, an accumulator machine and its supporting C compiler. The hypothesis of the Leros instruction set architecture is that it can deliver the same performance as a RISC pipeline, but consumes less hardware and therefore also less power.
