Abstract
Transfer of data blocks between a host and a multi-media card (“MMC”) are performed in a pre-defined mode. In pre-defined mode, the host sets a pre-determined number of blocks, a “multiblock,” to be transferred. Use of pre-defined mode results in faster transfers than those performed using an open-ended mode incorporating a stop command. Furthermore, corruption errors resulting from delays in providing the stop command which may occur in an open-ended mode are avoided. Pre-defined multiblock transfers are supported by existing operating systems through trapping open-ended mode transfers in the MMC stack, leaving existing device drivers unaffected.
