1.22. Partial and Dynamic Configuration
Partial reconfiguration allows you to reconfigure part of the FPGA while other sections continue running. This capability is required in systems where uptime is critical, because it allows you to make updates or adjust functionality without disrupting services.
In addition to lowering power and cost, partial reconfiguration also increases the effective logic density by removing the necessity to place in the FPGA those functions that do not operate simultaneously. Instead, these functions can be stored in external memory and loaded as needed. This reduces the size of the required FPGA by allowing multiple applications on a single FPGA, saving board space and reducing power. The partial reconfiguration process is built on top of the proven incremental compile design flow in the Intel® Quartus® Prime design software.
Dynamic reconfiguration in Intel® Agilex™ devices allows transceiver data rates, protocols and analog settings to be changed dynamically on a channel-by-channel basis while maintaining data transfer on adjacent transceiver channels. Dynamic reconfiguration is ideal for applications that require on-the-fly multiprotocol or multi-rate support. Both the PMA and PCS blocks within the transceiver can be reconfigured using this technique. Dynamic reconfiguration of the transceivers can be used in conjunction with partial reconfiguration of the FPGA to enable partial reconfiguration of both core and transceivers simultaneously.
