The 64-bit 21164A Alpha RISC that Digital Equipment Corp is using in its shiny new workstations expected on March 11, is a shrink of its 21164 CMOS5 process, although it gains only part of the advantage of the 0.35 micron, CMOS6 process. The 21164A is a CMOS5 design implemented in CMOS6, hence the EV56 notation. The StrongARM SA-110 announced back in February uses a ‘true’ 0.35 micron design. Meantime, 21164a’s support silicon is said to be an extension of the Alcor chip set.
