Project Name: Build Reliable Distributed SystemThe project goal is to build a distributed system that has both active and passive replication mode and tolerates 2 simultaneous server failures. The system includes 1 Replication Manager, 1 Global Fault Detector, 3 Local Fault Detectors, and 3 Servers.-Programmed logging and checkpointing of the system to prevent the loss of states, requests, or replies and to ensure consistency between replicas.-Coded membership tracking and propagation so that the system is capable of duplicate detection and is aware of failure of any servers or Local Fault Detectors. Heartbeat is used for fault detection.-Enabled the replication manager to automatically spawn new servers that are identical to the failed servers.

The purpose of this lab is to take an existing 8051 softcore and implement a System-On-Chip with Xilinx’s Artix-7 FPGA on the Basys3 board that uses the on-board ADC and communicates with a PC through UART.-Matched two different clock regions, 11.08MHz on 8051 and 100MHz on BRAM, using FIFO so that 8051 can read from theBRAM; otherwise, 8051 read 0s.-Designed and coded for a sequential logic that reads data from a 12-bit BRAM to 8051 using its 8-bit bus to enablememory fetching with a single memory accessing instruction in C51.- Set up UART on 8051 for 9600N81 to communicate with a PC through a terminal.- Programmed the 8051 softcore using Keil C51 to output the ADC reading on a PC terminal.
