General System Performance • Expectations – quick response to user interactions – efficient subsystems • Example expectations – Augmented Reality - low overhead – Authoring - accuracy – Modeling - efficient algorithm
Input/Output Performance • Response time to user interaction – user actions infrequent compared to automated tasks – no problems expected • Possible problems with data transfer rate – limited disk space on PEDD – IETM cannot be fully downloaded • 3 D card preferred but not necessary
Processor Allocation • Two most processor intensive operations – wireframe manipulation – speech recognition • Constrained by available PEDD – Pentium 233 MMX processor
Memory Allocation • Current PEDD constraints – 64 meg • No accurate estimates of the memory requirements of each subsystem • Should clarify itself as object design proceeds
Hardware Connectivity • The arrows indicate flow of information
