The PB8051 Microcontroller Core offers a robust implementation of the classic 8051 microcontroller, specifically for integration with Xilinx FPGAs. This core mimics the 8031 series microcontroller, including its serial port and two timers, maintaining software compatibility with the 8031. Its design harbors flexibility, able to execute existing 8051 object code, which ensures backward compatibility for legacy systems.
The PB8051 leverages the Xilinx PicoBlaze softcore microcontroller to provide a small footprint core design, making it approximately 28% the size of competing 8051 core implementations. This space-efficient design translates to a more cost-effective use of FPGA resources without hampering the core's capabilities. The PB8051 operates at increased speeds, achieving performance parity with traditional 8051s by functioning four times faster in clock frequency, translating into higher throughput for embedded operations.
A sophisticated architectural design supports use within all Xilinx FPGAs from the Spartan II series onwards. In addition, comprehensive documentation and reference designs are provided to support both novices and experienced engineers, ensuring ease of integration and rapid deployment. This microcontroller solution underscores Roman-Jones’ ability to blend heritage microcontroller functionality with contemporary FPGA technology, delivering a versatile and cost-effective product.
