Asynchronous DSPs: Low power, high performance

Keywords:DSP asynchronous logic core EDA tools

Asynchronous design has been avoided in the past for many reasons, the most important being the lack of a standardized tool flow. To deliver devices quickly, IC design teams use high-level programming languages in combination with EDA tools that speed tasks such as logic design. If such tools were available for asynchronous design, there would be more devices with asynchronous logic components.

This article makes the case for a general-purpose digital signal processor (DSP) core based entirely on asynchronous logic. It reveals many benefits, both for the IC designer and the end user.

What does asynchronous mean?
In an asynchronous circuit, parts are largely autonomous. They are not governed by any regular, periodic time-controlling mechanism, such as a clock circuit or signal, but instead need only wait for the signals that indicate completion of instructions and operations. These signals are often specified by simple data transfer protocols.
This digital logic design is contrasted with a synchronous circuit which operates according to clock timing signals.
