Are early computer architectures a source of ideas for low-power?

Many concepts and ideas were introduced for the design of the early computers after World War II. The interesting point is that some of these concepts and ideas are used today as low-power techniques for the design of low-power microprocessors or embedded microcontrollers. After a short history of the first computers, this paper describes the instruction sets that are similar to the modern RISC instruction sets. Some architectural features, such as pipelining, parallelism and asynchronous design, have been used for these early computers. Furthermore, parallel, interleaved and cache memories were also used due to limited throughput of a single memory block.
