DELFT-JAVA Link Translation Buffer

چکیده
We describe the hardware support in the DELFT-JAVA processor which enables efficient dynamic linking of JAVA programs. The proposed mechanism supports method invocation of dynamically linked classes through the use of a Link Translation Buffer (LTB). Since our Instruction Set Architecture directly supports dynamically linked method invocation, the Link Translation Buffer is architecturally transparent to the executing program. The operation of the LTB is described and preliminary performance results are reported. Method invocation differences between the C++ programming language and the JAVA programming language are outlined. Preliminary performance results for the Link Translation Buffer suggest that program performance may improve from 1.1x to 1.5x when a suitable LTB is used to cache frequently utilized methods.

This paper describes the DELFT-JAVA processor and the mechanisms required to dynamically translate JVM instructions into DELFT-JAVA instructions. Using a form of hardware register allocation, we transform stack bottlenecks into pipeline dependencies which are later removed using register renaming and interlock collapsing arithmetic units. When combined with superscalar techniques and multiple i...
