Teak: A Token-Flow Implementation for the Balsa Language

This paper describes a new target component set and synthesis scheme for the Balsa asynchronous hardware description language. This new scheme removes the reliance on precise handshake interleavingand enclosure by separating out control ´go´ and ´done´ signalling into separate channels rather than using different phases of the asynchronous handshake. This leads to circuits in which optimisation and control overhead mitigation can be carried out by merging/separating control and data channels and by introducing handshake-decoupling latches. This work aims to make Balsa descriptions implementable in the more widely used and understood higher performance token-based asynchronous circuit styles.
