Asynchronous circuits for low power: a DCC error corrector

Practical advances in asynchronous design and in asynchronous/synchronous interfaces

“…At Philips Research and Eindhoven University, van Berkel et al [68,69] have developed an industrial synthesis package, based on their Tangram language. The tool has been applied to both commercial and experimental designs, including a DCC error corrector and an 80C51 microcontroller (discussed in Section 3).…”

Asynchronous circuit design

“…So far, the work reported on low-power asynchronous design has focused on microprocessor design [3], [4], and on error-correcting codes [1], [2]. The latter is an area that is characterized by algorithms where the number of steps is data dependent and where multiple clocks are involved.…”

Stabilization of Lebesgue sampled systems with bounded controls: the chain of integrators case

“…The need of low power electronic components in all embedded and miniaturized applications encourages companies to develop asynchronous versions of existing time triggered components with significant power consumption reduction: about four times less power than its synchronous counterpart for the 80C51 microcontroller of Philips Semiconductors [van Gageldonk et al, 1998]. Moreover, the absence of synchronization considerably reduces noise and electro-magnetic emissions by improving the time repartition of the events [Van Berkel et al, 1994, 1999. Note that now sensors and actuators based on level crossing events exist rendering a complete asynchronous control loop possible.…”
