| Digital signal processing | Processes streams of sampled data using configurable arithmetic and logic circuits. | Filtering, transforms, modulation, and demodulation. | Many operations can run concurrently, which can support predictable, low-latency processing. | Performance depends on the chosen arithmetic precision, data flow, and available on-chip resources. |
| High-speed data acquisition | Captures, buffers, and preprocesses data from external converters or digital interfaces. | Sensor measurements, scientific instruments, and industrial monitoring. | Custom logic can be designed to match specific data formats and timing requirements. | External converters, clocking, and board-level signal integrity affect the complete system. |
| Communications and networking | Implements parts of communication protocols and processes packet or symbol data. | Packet classification, framing, error correction, and interface bridging. | Parallel pipelines can handle multiple processing stages with consistent timing. | Protocol complexity and interface standards determine the required logic and memory resources. |
| Real-time control | Reads inputs, applies control logic, and updates outputs according to a defined schedule. | Motor control, robotics, and industrial automation. | Dedicated hardware logic can provide deterministic response timing for time-critical tasks. | System safety, feedback-loop timing, and interaction with processors must be carefully designed. |
| Image and video processing | Applies configurable operations to pixel streams as images or video frames arrive. | Image enhancement, color conversion, and video-format conversion. | Pixel-level operations can be pipelined and performed in parallel. | Resolution, frame rate, memory bandwidth, and buffering requirements influence the design. |
| Custom digital interfaces | Creates logic for connecting systems that use different data formats, timing, or signaling protocols. | Protocol conversion, legacy-system integration, and custom peripheral interfaces. | Logic can be tailored to interface requirements that may not be served by a standard controller. | Electrical signaling requirements are separate from the digital logic and may require additional circuitry. |
| Hardware acceleration | Runs selected computational tasks in configurable hardware alongside a processor. | Repeated arithmetic, data transformation, and parallel algorithms. | Work can be divided into parallel operations instead of being executed only as a sequential software routine. | Acceleration depends on workload parallelism, data movement, and the effort required to develop and verify the hardware. |
| Prototyping and verification | Implements and tests digital circuit designs before a final hardware implementation. | Control logic, interface designs, and digital system prototypes. | The design can be revised and reprogrammed as requirements change. | Prototype behavior should be validated against the timing and electrical characteristics of the intended final system. |
