Indigo2 Indigo (tm) Family
Indigo2 systems come with the choice of two balanced high- performance processors; the MIPS(r) RISC R4400(tm)/150MHz processor or the R4000(r)/100 MHz processor. Both processors provide leading integer and floating point performance, fast on chip cache and a large 1MB secondary cache. Finally, to feed the bus and processor we have designed in two Fast SCSI-2 I/O channels along with a host of custom VLSI chips to efficiently manage and utilize the system's bandwidth and performance.
