The
Mariah chip set, an improvement on the Rigel chip
set, was manufactured in 1.0 micrometer CMOS
technology. The VAX 6500 processor delivered
approximately 13 times the power of a VAX-11/780
system, per processor. The 6500 systems (shown
here) implemented a new cache technique called
write-back cache, which reduced CPU-to-memory
traffic on the system bus, allowing
multiprocessor systems to operate more
efficiently. |
