Processor/Chip Set

The terminal uses an Intel architecture processor, which permits it to leverage existing software drivers and applications, as well as provide the greatest flexibility in choosing an operating system. This provides several other advantages:

•Capable of SW MPEG-1 playback at 30 frames per second with 22 KHz stereo audio (may be limited by OS constraints)

•Sound Blaster-compatible audio capability

•Java Benchmark performance > 1000 Caffeinemarks, JIT compiled

•OS support to run Java

•Expansion capabilities for optional features and future requirements (ISA/PCI bus and USB)

The following sections identify processors, system bus speed, and on- board memory available on 7454 Release 2.x processor boards:
