Understanding FPGA Working Principles in 10 Minutes
FPGA Configuration
-
Bitstream Loading
When the FPGA is powered on, the bitstream is loaded into the device’s configuration memory. This can be accomplished through various methods, such as on-chip non-volatile memory, external memory, or dedicated configuration devices.
-
Configuring Logic Blocks and Interconnections
Once the bitstream loading is complete, the configuration data will configure the FPGA’s logic blocks and interconnections to realize the desired digital circuit. This process effectively “programs” the FPGA to perform the intended functions.
