If software is king for systems-on-silicon, what's new in compilers?

While software if already a significant component in today's system-on-silicon, it is expected to greatly dominate future generations of systems-on-silicon that will contain several (possibly heterogeneous) programmable processors, as well as reconfigurable hardware blocks and large amounts of on-chip memory. In this context, one could argue that the problems for compiler designers haven't changed at all, since the basic issues all boil down to the traditional challenges of 1) coarse-grain parallelism extraction for the multiple processors on drip, 2) instruction-level parallelism exploitation for individual processors, and 3) retargetable code generation for versions of the on-chip processors. This paper summarizes the positions of the panelists rt ho presented their views on the new challenges in compilers for future systems-on-silicon, and who debated these issues ar ICCD'97.
