Dynamic Binary Translation for Accumulator-Oriented Architectures
A dynamic binary translation system for a co-designed virtual machine is described and evaluated. The underlying hardware directly executes an accumulator-oriented instruction set that exposes instruction dependence chains (strands) to a distributed microarchitecture containing a simple instruction pipeline. To support conventional program binaries, a source instruction set (Alpha in our study) is dynamically translated to the target accumulator instruction set. The binary translator identifies chains of inter-instruction dependences and assigns them to dependence-carrying accumulators. Because the underlying superscalar microarchitecture is capable of dynamic instruction scheduling, the binary translation system does not perform aggressive optimizations or re-schedule code; this significantly reduces binary translation overhead. Detailed timing simulation of the dynamically translated code running on an accumulator-based distributed microarchitecture shows the overall system is capab...
