What Fujitsu Laboratories has developed is a platform for running simulations that allows for cycle-level simulations with low system overhead, based on a
just-in-time compiler. The end result is that a standard PC environment can simulate at the cycle level an ARM multicore system running at faster than 100 MHz, which represents a hundredfold speedup over previous simulators.

just-in-time compiler, IBM Systems Journal, vol.
Inprise/Borland customers will be able to take advantage of the latest Java 2 platform, including new IBM technology such as a
just-in-time compiler and re-engineered Java 2 virtual machine.
The kit includes a Java Virtual Machine (JVM), a
just-in-time compiler and a mixed mode interpreter.
At the same time, Microsoft added an enhanced version of its JIT
just-in-time compiler, which it claims will keep its performance lead of 30% compared with the "most recent offerings" from its competitors.
IBM has also hinted that a
just-in-time compiler is in the works, which will not only compile Java but which should improve its comparatively sluggish performance.
