Interface for additional Special Function Registers DP80C51 is an ultra high performance, speed optimized soft core of a single-chip 8bit embedded controller dedicated for operation with fast (typically on-chip) and slow (offchip) memories. The core has been designed with a special concern for performance to power consumption ratio. This ratio is extended by an advanced power management unit PMU. DP80C51 soft core is 100% binary and pin compatible with the industry standard 8051 8-bit microcontroller. There are two configurations of the DP80C51: Harward, where external data and program buses are separated, and von Neumann, with common program and external data bus. DP80C51 has Pipelined RISC architecture up t...
