AI Engine Intrinsics User Guide
(AIE) r2p23
|
These intrinsics enable the AI Engine to access the input/output streams. Some of these intrinsics are "blocking" and will stall the AIE when trying to read from an empty stream, or write to a full one. Non blocking intrinsics have "_nb" in their name.
Concerning performance :
Packet headers | |
These intrinsics are designed to facilitate the headers creation. They do not write directly to stream and should always be combined with a "put_ms" call. | |

idx_ms | master ports |
tlast | The optional tlast parameter indicates the last word in a packet and the default is false. |
Addr | unsigned Local Byte Address (two LSB not used). Accesses are 128 bit aligned. |
n_words | unsigned 2 bits. 1 to 4 words of 32 bit data to follow. This must be a compile time constant. |
op_type | unsigned Operation modes - 2 bit (LSB). 3 modes. 0 - Write without return, 1 - Read with return, 2 - Write with return. The response to a read will be a packet switched stream header and 1 to 4 32 bit word data. The response to a write will be a packet switched stream header. This must be a compile time constant. |
rspID | unsigned Response ID: 5 bit (LSB). Identifies the return destination for operation modes with a return. (The return packet's header's 'dstID' is set to this). |
This intrinsic takes an address, number of words, operation type and response ID and returns a control packet header.
