Abstract
A memory unit includes a data storage to store data, an operation controller to receive operation requests issued by an upstream source, a downstream capabilities storage to store an indication of operations performable by at least one downstream memory unit, and processing circuitry to perform operations on data stored in the data storage under control of the operation controller. When an operation request to perform an operation on target data is received from the upstream request source, the operation controller is arranged to determine when to control the processing circuitry to perform the operation, and when to forward the operation to a downstream memory unit in dependence on whether the target data is stored in the data storage unit and the indication of operations performable by at least one downstream memory unit. This allows for operations to be executed at a suitable location within a memory system, taking into account not only where the data resides, but also the complexity of the operation and the capabilities of the processing circuitry provided at various memory locations within the memory system.
