I describe a new compiler infrastructure for imperative synchronous languages such as Esterel and ecl. Built on the suif 2 system, it includes a new intermediate representation fo...
If S = 0 is a system of n equations and unknowns over C and S() = 0 to what extent can we compute with the point ? In particular, can we decide whether or not a polynomial express...
We show that the basic feasible functions of Cook and Urquhart's BFF [8,9] are precisely the functionals definable in a natural system of ramified recurrence that uses type i...
An approach to software composition from heterogeneous components is presented. The focus is on heterogeneity of interaction styles. The interface of a component is described in an...
We show that the traditional notion of superposition as used for supporting parallel program design can subsume both composition and refinement relationships when non-deterministi...
