FPGA: what it means.
An FPGA contains logic elements and routing controlled by configuration memory. AMD describes loading a bitstream to specify the device’s implemented functions. Logic resources can range from simple combinational functions to embedded processing resources. (AMD: FPGA architecture)
Writing software for a processor and configuring an FPGA are different implementation activities. A design may include both, but hardware configuration determines how FPGA resources are connected and used. (AMD: FPGA architecture)
Put the definition to work.
Reading “FPGA” tells you the broad device class. For an actual design, use the manufacturer’s documentation to determine the available logic resources, interfaces, package, and configuration requirements.
Questions to ask next.
Use these questions as a reading checklist, not as a device-selection recommendation. Exact manufacturer documentation takes priority over a general definition.
- Available logic and interface resources
- Configuration and development workflow
- Timing and device-specific constraints

Common FPGA questions.
Does FPGA mean that no CPU can be present?
No. FPGA architecture can include processing resources, and complete systems can combine programmable logic with processors. Read the specific architecture rather than assuming one exclusive role. (AMD: FPGA architecture)
