Re: Java execution acceleration

A broader range of optimizations is possible with JIT and HotSpot technologies than can
be achieved with hardware acceleration that focuses on optimizing evaluation of individual
bytecodes.  Runtime optimization techniques can target optimizations to frequently used methods,
inline to avoid method calls, do subexpression
optimization/elimination, move common subexpressions out of loops, etc. just to name
a few simple ones.  VM implementations are need flexibility in the representation of Objects,
flags and support for synchronization primitives to optimize performance and provide
alternatives in GC and synchronization.  A combination of hardware and software could
have greater improvements but once a mechanism is embedded in hardware it ends up constraining
the possible VM design.
