The company promoted its Java support at the JavaOne conference in San Francisco during a keynote presentation. AMD is working on improvements in compilers, operating systems, middleware and development tools as well as Java Virtual Machine improvements. AMD is finding ways to improve Java performance across multi-core environments and has been researching improvements in garbage collection, according to AMD. Garbage collection involves the discarding of objects from memory after they are no longer needed or referenced.
"AMD understands that good software is critical to our product roadmap," said Leendert van Doorn, a senior AMD fellow. Without software, silicon just conducts energy, he said.
Multi-threaded programming "is inherently easier to do in Java," because of Java's built-in support for concurrent programming, van Doorn said.
But there are hurdles to overcome in application performance, said van Doorn. "This is an issue we're working on to help address," he said.
AMD has proposed its Light-Weight Profiling software parallelism specification to help managed code like Java run more efficiently by using continuous performance feedback. Also, AMD's Advanced Synchronization Facility proposal increases software concurrency.
