The Buffers table contains
information related to the buffers that are mapped to the ADF graph. Typically,
buffers are used in window connections.
Note: The use of
buf# and buf#d
means it is a ping-pong buffer.Figure 1. Buffers Table
| Column | Description |
|---|---|
| Name | The name of the connection where the buffer is allocated. |
| ID | The unique ID given to the buffer by the AI Engine compiler. |
| Type | The type of buffer being used. This can either be Memory or Stream. The connection to a window uses a ping-pong buffer, and connection to a stream might use a DMA buffer. |
| Net | The net with which the buffer is associated. |
| Column | The column location of the tile where the buffer is mapped by the compiler. |
| Row | The row location of the tile where the buffer is mapped by the compiler. |
| Bank | The bank of the tile where the buffer is mapped. The banks are:
0,1,2, or 3. Note: The
hardware view is 8 banks of 128 bit width. The software view is
4 banks of 256 width.
|
| Offset | The address offset of the buffer with the bank. |
| Size | The size of the buffer in bytes. |
| Lock ID | Unique ID per buffer if placed in the bank. |
| Lock Name | The unique name of the lock associated with the buffer. This can be used to debug a lock stall on a buffer. |
