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.

Packet headers

Function Documentation

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

Generate a control packet header.

Parameters
Addrunsigned Local Byte Address (two LSB not used). Accesses are 128 bit aligned.
n_wordsunsigned 2 bits. 1 to 4 words of 32 bit data to follow. This must be a compile time constant.
op_typeunsigned 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.
rspIDunsigned 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.

Please use 'void put_ms_ctrl_packet_header(int, int, unsigned, unsigned, unsigned, unsigned)' instead.

unsigned int packet_header ( unsigned  dstID,
unsigned  pcktType 
)

Generate a packet header.

Parameters
dstIDunsigned 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.
pcktTypeunsigned 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.
Deprecated:
Please use 'void put_ms_packet_header(int, int, unsigned, unsigned)' instead.

void put_ms ( int  idx_ms,
float  a 
)

Write a 32-bit value to output stream port MS0 or MS1 The optional tlast parameter indicates the last word in a packet and the default is false. Intrinsics suffixed with _nb perform a non-blocking write. All others are blocking.

void put_ms_ctrl_packet_header ( int  idx_ms,
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_msmaster ports
tlastThe optional tlast parameter indicates the last word in a packet and the default is false.
Addrunsigned Local Byte Address (two LSB not used). Accesses are 128 bit aligned.
n_wordsunsigned 2 bits. 1 to 4 words of 32 bit data to follow. This must be a compile time constant.
op_typeunsigned 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.
rspIDunsigned 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.
void put_ms_ctrl_packet_header ( int  idx_ms,
unsigned  Addr,
unsigned  n_words,
unsigned  op_type,
unsigned  rspID 
)

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

Parameters
idx_msmaster ports
tlastThe optional tlast parameter indicates the last word in a packet and the default is false.
dstIDunsigned 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.
pcktTypeunsigned 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.
