Abstract

 In order to match application software with the underlying hardware, we propose to use run time information to better design processors and accelerators, while still allowing for binary compatibility to obtain gains at the system level. Two main techniques are explored in this proposal, which are hardware algorithms for mapping and P&R in fine grain devices, and binary translation coupled with reconfiguration for coarse grain devices. As the hardware itself is responsible for its adaptation to the new scenario, this opens up several application possibilities besides optimum execution times or energy efficiency. We will show two case studies that explore the initial ideas of this work, and discuss the problems that lie ahead of this adaptive computing path. One case study is a JIT modulo scheduling algorithm for inner loop acceleration. The second case is a runt-ime FPGA placement and routing.
