1. A computing memory, comprising: an execution unit for processing operand data; and an access processor coupled with a memory system for providing operand and configuration data to the execution unit, wherein the execution unit and the access processor are logically separated units, and wherein the access processor reads operand data from the memory system and sends these data to the execution unit which executes operations on the operand data according to the provided configuration data, and wherein the access processor has information about execution times of operations of the execution unit for the provided configuration, and wherein the access processor reserves time-slots for writing execution unit results provided by the execution unit into selected locations in the memory system based on the information about the execution times, at the time of sending the data to the execution unit.
