The V830 microprocessor is the first member of NEC’s V830
TM
family of 32-bit RISC microcontrollers.
The high-performance, low-power V830 microprocessor with DSP features and on-chip caches is
ideally suited for low-cost embedded applications. The high processor bandwidth allows the V830 to
target multimedia applications such as J PEG decoding and Internet-based information appliances. DSP
functionality is provided with a 32-bit hardware barrel shifter and a single-cycle, multiply-and-accumu-
late (MAC) instruction executing up to 200 million operations per second (MOPS).
