Stored state asynchronous sequential circuits
Journal ArticleA method is described for realizing asynchronous sequential circuits in a manner analogous to the stored state method for synchronous sequential circuits. the method simplifies the process of constructing asynchronous sequential circuits, allows utilization of existing MSI parts, and avoids the necessity for concern with races or hazards
Soft thought (in architecture and choreography)
This article is an introduction to and exploration of the concept of âsoft thoughtâ. What we want to propose through the definition of this concept is an aesthetic of digital code that does not necessarily presuppose a relation with the generative aspects of coding, nor with its sensorial perception and evaluation. Numbers do not have to produce something, and do not need to be transduced into colours and sounds, in order to be considered as aesthetic objects. Starting from this assumption, our main aim will be to reconnect the numerical aesthetic of code with a more âabstractâ kind of feeling, the feeling of numbers indirectly felt as conceptual contagionsâ, that are âconceptually felt but not directly sensed. The following pages will be dedicated to the explication and exemplification of this particular mode of feeling, and to its possible definition as âsoft thoughtâ
Asynchronous Logic Design with Flip-Flop Constraints
Some techniques are presented to permit the implementation of asynchronous sequential circuits using standard flip-flops. An algorithm is presented for the RS flip-flop, and it is shown that any flow table may be realized using the algorithm (the flow table is assumed to be realizable using standard logic gates). The approach is shown to be directly applicable to synchronous circuits, and transition flip-flops (JK, D, and T) are analyzed using the ideas developed. Constraints are derived for the flow tables to meet to be realizable using transition flip-flops in asynchronous situations, and upper and lower bounds on the number of transition flip-flops required to implement a given flow table are stated
