High Performance: Writing a Sony PlayStation Emulator in Java Technology
TS-5547

A PlayStation emulator requires lightning-fast 2-D and 3-D graphics (up to 60 fps), accurate timing, multichannel sound, and streaming video. This case study explores some of the challenges, solutions, and lessons learned while implementing a full-speed PlayStation emulator in pure Java technology.

• - Marrying object orientation and speed
• - Cool Java technology-based stuff, such as NIO and VolatileImage
• - Taking full advantage of optimizations in Java technology's native compiler
• - Cross-platform issues
• - Java technology-based bytecode generation
• - Cool emulator stuff, such as a runtime-profiling-based optimizing R3000 to bytecode compiler

Many of the strategies covered are applicable to mainstream Java technology-based applications, not just Java technology-based games.

Note: This talk does not contain specific technical details of the PlayStation software or hardware.
