Electronic system level (ESL) modeling allows early hardware-dependent software (HDS) development. Due to broad CPU diversity and shrinking time-to-market, HDS development can neither rely on hand-retargeting binary tools, nor can it rely on pre-existent tools within standard packages. As a consequence, binary utilities which can be easily adapted to new CPU targets are of increasing interest. We present in this article a framework for automatic generation of binary utilities. It relies on two innovative ideas: platform-aware modeling and more inclusive relocation handling. Generated assemblers, linkers, disassemblers and debuggers were validated for MIPS, SPARC, PowerPC, i8051 and PIC16F84. An open-source prototype generator is available for download.

Emergingdesign problems are prompting the use of code motion and speculative execution in high-level synthesis to shorten schedules and meet tight timeconstraints.However, some code motions are not worth doing from a worst-case execution perspective. We propose a technique that selects the most promising code motions, thereby increasing the density of optimal solutions in the search space.
