Detailed Description

Node object descriptor.

Fields with name target_* are only accessed by target CPU Fields with name host_* are only accessed by host CPU Other fields are accessed by both target and host

Field Documentation

node_complete_cmd_obj_desc_id

volatile uint32_t tivx_obj_desc_node_t::node_complete_cmd_obj_desc_id

command to send when node completes execution

This is set by host in following conditions

• when user callback is attached and host wants intimation of node execution complete in order to call user callback
• when this is a leaf node and host needs intimation of node execution complete in order to check for graph execution complete

Definition at line 374 of file tivx_obj_desc.h.

target_kernel_index

volatile uint32_t tivx_obj_desc_node_t::target_kernel_index[TIVX_NODE_MAX_REPLICATE]

Index in target kernel table.

Used for fast indexing to kernel functions during graph execute phase.

This is filled by target side during node create phase
