Systems and methods for looping dynamic memory access operations

A coarse-grained reconfigurable (CGR) processor (CGRP) comprising:

• a direct memory access (DMA) engine configured to process a work queue (WQ) that is configured to store a plurality of work queue elements (WQEs);
• and
• a processor configured to write a work queue element (WQE) to the WQ, the WQE including a jump_wait indicator, wherein:
• the DMA engine is configured to enter a jump_pause state in response to processing the WQE and determining that the jump_wait indicator is set;
• the DMA engine is configured to identify one of the WQEs based at least in part on a jump offset in a trigger message;
• and
• the DMA engine is configured to enter a run state and to begin processing the one of the WQEs in response to receiving the trigger message.

A method implemented by a direct memory access (DMA) engine, the method comprising:

• reading a work queue element (WQE) that is in a work queue configured to store a plurality of WQEs;
• entering a jump_pause state in response to processing the WQE and determining that a jump_wait indicator in the WQE is set;
• using a jump offset included in a trigger message to identify one of the WQEs in response to receiving the trigger message;
• and
• entering a run state and beginning to process the one of the WQEs in response to receiving the trigger message.
