Chapter 6 — Component Interfaces & Behavior - Chapter 6 — Component Interfaces & Behavior - 2026.1 English - UG1864

VFS components can expose stream or buffer interfaces, and each has its own rules for how partial, exact, and oversized data are handled. This chapter is the reference for that behavior.

• HLS stream vs buffer interfaces — how hls::stream<T> and array-based interfaces differ in VFS.
• AIE stream vs buffer interfaces — the analogous discussion for AIE graphs (streams, windows, and buffers).

Read this chapter once you start writing your own kernels or graphs — understanding it will save you a lot of debugging time.
