While there are well-understood methods for detecting loops whose iterations are independent and parallelizing them, there are comparatively fewer proposals that support parallel execution of a sequence of loops or nested loops in the case where such loops have dependencies among them. This paper introduces a refined notion of independence, called eventual independence, that in its simplest for...
We present a novel scheme for the solution of linear differential equation systems on parallel computers. The Implicit Pipeline (ImP) method uses an implicit timeintegration scheme coupled with an iterative linear solver to solve the resulting differential algebraic system. The ImP method then allows for two independent mechanisms for parallelism: pipelining of the solution of several timesteps...

Embedding register-pressure control in software pipelining heuristics is the dominant approach in modern back-end compilers. However, aggressive attempts at combining resource and register constraints in software pipelining have failed to scale to real-life loops, leaving weaker heuristics as the only practical solutions. We propose a decoupled approach where register pressure is controlled bef...
Design of a high performance and high-density multiplier is presented. This multiplier is constructed by using the Wallace tree structure with pipelining. A fast carry select adder is used for the final two-operand adder. It is shown that the time delay for the entire multiplier is O(log(n)). The design is particularly carried out for a 32-bit multiplier with two sections of pipelining, to bala...
Modern processors, especially VLIW processors, often have the ability to execute multiple instructions simultaneously. Taking advantage of this capability is crucial for high performance software applications. Software pipelining is a technique designed to increase the level of parallelism in loops. We propose a new approach to software pipelining based on direct manipulations of control flow g...
Sissades Tongsima Nelson L. Passos Edwin H-M. Sha Dept. of Computer Science & Engineering University of Notre Dame Notre Dame, IN 46556 Abstract Loop pipelining (retiming) is a valuable tool used to explore parallelism across iterations. Few results are available about loop pipelining with data communication considerations. This paper rst designs a modi ed list scheduling algorithm to be used a...
The IEEE-754 standard floating point multiplier that provides highly precise computations to achieve high throughput and low area on the IC have been improved by insertion of pipelining technique. Floating point multiplier-using pipelining has been simulated, analyzed and its superiority over traditional designs is discussed. To achieve pipelining, one must subdivide the input process into sequ...
