System

The Sun Blade 100 system is an UltraSPARC port architecture-based uniprocessor
machine that uses the peripheral component interconnect (PCI) as the I/O bus. The
CPU and ATI graphics ASIC communicate with each other using the UPA64S and
PCI protocols.
The following figure shows a functional block diagram of the system.
