TLDR
Sehwa can find the minimum-cost design, the highest performance design, and other designs between these two in the design space and executes within minutes, for problems of practical size, on a VAX 11/750.Abstract:
A set of techniques for the synthesis of pipelined data paths is described, and Sehwa, a program that performs such synthesis, is presented. The task includes the generation of data paths from a data-flow graph along with a clocking scheme that overlaps execution of multiple tasks. Some design examples are given. Sehwa can find the minimum-cost design, the highest performance design, and other designs between these two in the design space. Sehwa is written in Franz Lisp and executes within minutes, for problems of practical size, on a VAX 11/750. >read more

Harmonic scheduling of linear recurrences for digital filter design
TL;DR: A novel approach, harmonic scheduling, is presented to generate optimal schedules for digital filters described by second-order difference equations with resource constraints, which exploits parallelism in these recurrences beyond loop-carried dependencies.

Synthesis of configurable architectures for DSP algorithms
TL;DR: This work presents a methodology to synthesize ASIPs for DSP algorithms and shows that such an architecture is weakly programmable (configurable) and can be viewed as an application specific instruction-set processor (ASIP).

Exploiting Bit-Level Delay Calculations to Soften Read-After-Write Dependences in Behavioral Synthesis
TL;DR: A presynthesis optimization algorithm that relaxes RAW dependences, taking advantage of this feature for a more efficient HLS of data flow graphs formed by additions, multiplications, and logic operations is proposed.

First version of a data flow procedure language
TL;DR: The language is being used as a model for study of fundamental semantic constructs for programming, as a target language for evaluating trans-latability of programs expressed at the user-language level, and as a guide for research in advanced computer architecture.
