Pipelined High Performance Microcontroller

The DP80C51 is an ultra high performance, speed optimized soft core, of a single-chip 8-bit embedded controller, intended to operate with fast (typically on-chip) and slow (off-chip) 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 PMU unit. The DP80C51 soft core is 100% binary and pin compatible with the industry standard 8051 8-bit microcontroller. There are two configurations of the DP80C51: Harvard, where external data and program buses are separated, and von Neumann, with common program and external data bus. The DP80C51 has a Pipelined RISC architecture, up to 10 times faster, comparing to standard architecture and executes 85-200 million instructions per second. This performance can also be exploited to great advantage in low power applications, where the core can be clocked over ten times slower than the original implementation, without performance depletion. The DP80C51 is delivered with fully automated testbench and complete set of tests, allowing easy package validation at each stage of SoC design flow.

Each of the DCD's 8051 Core has a built-in support for DCD Hardware Debug System, called DoCD . It is a real-time hardware debugger, which provides debugging capability of a whole System on Chip (SoC).
Unlike other on-chip debuggers, the DoCD provides non-intrusive debugging of running application. It can halt, run, step into or skip an instruction, read/write any contents of microcontroller, including all registers, internal and external program memories, all SFRs, including user defined peripherals.
