NEC V60 (Paperback)

High Quality Content by WIKIPEDIA articles! The NEC V60 ( PD70616) was a CISC processor manufactured by NEC introduced in the late 1980s. It had a 32-bit internal bus and a 16-bit external bus with a 24-bit address bus. A relatively obscure design, it was a radical departure from NEC's previous V-series CPUs (such as the NEC V20), most of which were based on the Intel x86 model. According to NEC's documentation, the change was made due to the increasing demand and diversity of programs, calling for a processor with both power (the 32-bit internal bus) and flexibility (having large numbers of general-purpose registers-a common feature of RISC architectures and a benefit to the emerging high-level languages). Despite its obscurity, it was the first 32-bit general-purpose microprocessor to be mass-produced in Japan, and information about the processor has slowly been accumulated through a combination of reference materials and reverse engineering.
