In the following, we continue to discuss the realization of the proposed large-scale CRNG in Figure 5. First, we construct ten sets (n = 10) of CRNGs by using the HT32F1765 microcontroller as shown in Figure 6. The HT32F1765 operates at a frequency up to 72MHz with a Flash accelerator to obtain maximum efficiency. It provides 128KB of embedded Flash memory for code/data storage and up to 64 KB of embedded SRAM memory for system operation and application program usage.
