NVAX

The NVAX is a microprocessor developed and fabricated by Digital Equipment Corporation (DEC) that implemented the VAX instruction set architecture (ISA). The NVAX was a high-end single-chip VAX microprocessor. A variant of the NVAX, the NVAX+, differed in the bus interface and external cache supported, but was otherwise identical in regards to microarchitecture. The NVAX is clocked at frequencies of 83.3 MHz (12 ns), 74.4 MHz (14 ns) and 62.5 MHz (16 ns), while the NVAX+ is clocked at a frequency of 90.9 MHz (11 ns).
