Abstract: A register bank of a channel of a direct memory access circuit is initialized. Transfer cycles are executed as configured by the register bank, and updates are made to the registers from a memory. At each transfer cycle, an operation is performed in accordance with a first field of the register bank to either: carry on the execution or generate a first signal and suspend the execution. In response to each reception of the first signal by a central processing unit, an operation is performed to either: generate a second signal or modify the content of the register band and/or record into the memory a first item representative of a next update of the register bank. A second signal is then generated.

Abstract: Storage space is reclaimed by cleaning and compacting data objects where data objects are stored by immutable storage. A storage area of which space needs to be reclaimed is identified. Active and stale data objects stored in a storage area are identified, and only active data objects are transferred to a shadow storage area from the storage area when recovering storage space. I/O operations can be fulfilled from the storage area and the shadow storage area. Compaction requests and I/O requests are throttled according to QOS parameters. Recovery of storage space does not cause a failure to meet performance requirements for any storage volume.

Abstract: When a data request signal is inactivated while a DMA controller is executing DMA data transfer in a burst transfer mode, an address at this time is held and a remaining number of transfer times is counted.

This makes it possible to re-transfer data remaining at the timing when the data request signal is inactivated, and the DMA data transfer using the burst transfer mode is executed to or from a module requesting the DMA data transfer by using level of the data request signal.

The selector value determines the credit values written back to the memory unit.
