## Overview

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 :

- 32-bit streams can be read/written every clock cycle.
- 128-bit streams can be read/written every 4 clock cycles.

## 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.
unsigned int | packet_header (unsigned dstID, unsigned pcktType)
| Generate a packet header.

## Function Documentation

## ◆ ctrl_packet_header()

unsigned int ctrl_packet_header | ( | unsigned | Addr,
|  | unsigned | n_words,
|  | unsigned | op_type,
|  | unsigned | rspID )

Generate a control packet header.

Parameters

  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.

Note
  Parameters 'n_words' and 'op_type' must be compile time constants.

## ◆ packet_header()

unsigned int packet_header | ( | unsigned | dstID,
|  | unsigned | pcktType )

Generate a packet header.

Parameters

  dstID | unsigned 5 bit (LSB). Identifies the destination of the packet. Should be unique amongst all streams it shares ports with. Can be 32 destinations or more with nested headers.
  pcktType | unsigned 3 bit (LSB). Can be used to distinguish packets with the same source and destination. Control packets set this to 7 if there is an error. This must be a compile time constant.

This intrinsic takes a destination ID and a packet type and returns a packet header.

Note
  Parameter 'pcktType' must be a compile time constant.
  A packet with nested headers has a number of headers at the beginning (instead of the usual single header). For every level of header nesting, the number of possible destinations is multiplied by 32, thus for a two-nested header approach, the number of destinations is already 1024.

## ◆ put_ms_ctrl_packet_header() [1/2]

|  | int | tlast,
|  | unsigned | Addr,
|  | unsigned | n_words,
|  | unsigned | op_type,
|  | unsigned | rspID )

Generate a control packet header and Write to 32-bit streams.

Parameters

  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.

Note
  Parameters 'n_words' and 'op_type' must be compile time constants.

## ◆ put_ms_ctrl_packet_header() [2/2]

void put_ms_ctrl_packet_header | ( | int | idx_ms,
|  | unsigned | Addr,
|  | unsigned | n_words,

|  | unsigned | rspID )

Generate a packet header and Write to 32-bit streams.

Parameters

  idx_ms | master ports
  tlast | The optional tlast parameter indicates the last word in a packet and the default is false.
  dstID | unsigned 5 bit (LSB). Identifies the destination of the packet. Should be unique amongst all streams it shares ports with. Can be 32 destinations or more with nested headers.
  pcktType | unsigned 3 bit (LSB). Can be used to distinguish packets with the same source and destination. Control packets set this to 7 if there is an error. This must be a compile time constant.

This intrinsic takes a destination ID and a packet type and returns a packet header.

Note
  Parameter 'pcktType' must be a compile time constant.
  A packet with nested headers has a number of headers at the beginning (instead of the usual single header). For every level of header nesting, the number of possible destinations is multiplied by 32, thus for a two-nested header approach, the number of destinations is already 1024.
