A Simple Value Range Propagation Pass for SUIF-1
نویسنده
چکیده
Reconfigurable Computing (RC) uses reconfigurable logic devices such as FPGAs to assist generalpurpose computation. In order to make efficient use of FPGA resources, it is essential to size datapaths and functional units to the minimal possible bitwidth that will ensure correctness. Since the high-level languages used to program RC systems do not require (or even allow) the user to manually specify datapath widths, the compiler must infer them. This paper presents a simple dataflow analysis for determining datapath widths in C programs and offers a preliminary SUIF-based implementation.

متن کاملCompiling Java to SUIF: Incorporating Support for Object-Oriented Languages
A primary objective in the SUIF compiler design has been to develop an infrastructure for research in a variety of compiler topics including optimizations on object-oriented languages. However, the task of optimizing object-oriented languages requires that high-level object constructs be visible in SUIF. Java is a statically-typed, object-oriented and interpreted language that has the same requ...
