Method and system for direct memory access

A computing system arranged to:

• identify an address in a set of addresses of a first address space of a memory of the computing system from a data packet comprising data to be written to the memory of the computing system and address data comprising the address;
• identify a subset of the set of addresses of the first address space with a subset of addresses of a second address space associated with the memory of the computing system;
• determine an address from a further subset of addresses in the second address space;
• determine a number of addresses of the second address space in the further subset;
• replenish the further subset when a number of addresses falls below a threshold number;
• write the data to a region of the memory associated with the determined address;
• and
• communicate a message to the computing system to update an address translation table on the computing system on the basis of the determined address.

• determine an address from a further subset of addresses in the second address space, including requesting the address and, in response, receiving address data for the address;
• write the data to a region of the memory associated with the determined address;
• and
• communicate a message to the computing system to update an address translation table on the computing system on the basis of the determined address.
