....8400 have a 16 byte L3 cache bus that cycles at a 75MHz clock rate [FFG 95] The 75 MHz R8000 processors in the Power Challenge have a 16 byte L2 cache bus cycling at 75 MHz. The R8000 is split into two chips with the separate floating point unit chip connected directly to the L2 cache [Gwe93] All the floating point loads and stores used in the STREAM benchmark do not access the L1 cache on the integer unit chip. The 167MHz UltraSPARC processors in the Sun UE 6000 system have a 16 byte L2 cache bus cycling at 167MHz. The fourth column gives the maximum aggregate application memory ....
....and data page faults. 4.6.1 Handling Vector Arithmetic Traps Without some form of revocable register renaming, a vector machine will not be able to provide precise vector arithmetic traps without a large performance loss. Some scalar systems make precise traps a user selectable mode [WD93, Gwe93] In this mode, further instruction issue must be delayed until all ongoing operations are known not to require a trap. This scheme can also be used in a vector machine. Whereas a scalar machine must delay after every operation, a vector machine is only delayed once per vector, but this delay can ....
