Interfaces

Interfaces in High-Level Synthesis (HLS) are crucial components that define how a hardware module communicates with other modules or the external environment. They play a vital role in determining the overall performance and functionality of the synthesized hardware.
Interfaces in HLS can range from basic unsynchronized wires linked to Control/Status Registers, to more advanced streaming, SRAM, and bus-based interfaces. Effective data movement plays a crucial role in optimizing bandwidth and overall system-level performance. Common HLS interfaces often use channels or connections with clear ready/valid/data signaling, enabling structured communication and efficient design implementation.
