Abstract
Methods and systems are provided for reducing partial cache writes in transferring incoming data status entries from a peripheral device to a host. The methods comprise determining a lower limit on a number of available incoming data status entry positions in an incoming data status ring in the host system memory, and selectively transferring a current incoming data status entry to the host system memory using a full cache line write if the lower limit is greater than or equal to a first value. Peripheral systems are provided for providing an interface between a host computer and an external device or network, which comprise a descriptor management system adapted to determine a lower limit on a number of available incoming data status entry positions in an incoming data status ring in a host system memory, and to selectively transfer a current incoming data status entry to the host system memory using a full cache line write if the lower limit is greater than or equal to a first value.
