Objective The objective of EXACT is to demonstrate that asynchronous circuit techniques (ie circuits that do not use a clock) can be exploited to: - reduce power consumption in microsystems applied to digital signal and data processing. - specify and design high-performance I/O interface circuits between both synchronous and asynchronous VLSI subsystems.Micropipeline and handshake circuit architectures have been compared, the possibility of blending these 2 styles investigated. Design techniques and computer aided design (CAD) tools for the automatic synthesis of asynchronous control circuits for interface applications have been developed. The following have been constructed: Benchmark circuits to compare the various approaches to asynchronous circuit design; a prototype compiler for asynchronous interface control circuits; several asynchronous implementations of the 12 C input/output (I/O) expander; a formal specification and prototype silicon for the digital compact cassette (DCC) error detector (consuming only 2.5 mW, 80% less than the synchronous integrated circuit (IC).The specific goals of the EXACT project are to contribute to solving the energy consumption/dissipation problem in digital data and signal processing; to develop novel techniques and tools for system interfacing; to show that asynchronous circuits can be built in a disciplined way; and to demonstrate the claimed power-saving properties in a commercially relevant application. The approach is to: - compare the micropipeline and handshake-circuit architectures, and to investigate the possibility of blending these two styles - develop design techniques and CAD tools for the automatic synthesis of asynchronous control circuits for interface applications (the commercial exploitation of these tools will be investigated as well) - design and manufacture two demonstrator circuits: . an I2C I/O expander (Philips PCF 8574) . an error detector based on DCC (Digital Compact Cassette) specifications in order to demonstrate the feasibility and low power potential of the methods.
