NEC V30 processor family

NEC V30 is a 16-bit CMOS microprocessor, object-code compatible and pin-compatible with Intel 8086. The V30 runs at the same speed as the 8086, but it's 10% - 30% faster (depending on application) due to internal improvements - dual internal 16-bit data bus, faster effective address calculation, faster integer multiplication and some others. The V30 includes Intel 8080 emulation mode, in which it can execute all of the 8080 instructions. Native V30 instruction set includes all 8086/8088 instructions, new instructions from the 80186/80188 microprocessor, and instructions unique to V30 - bit processing, packed BCD instructions and special instructions for switching the processor to 8080 emulation mode and back.
