摘要： The present invention includes a method of transferring data when some of the data is masked. A mask table is provided to a storage device where it is duplicated and stored with the duplicate. The duplicate data is compared to the original data for a data protection function. A mask index counter and mask bit counter maintain provide values for specific data that are to be processed. The counters are programmable so that if a transfer error occurs, counter values for the next data after the previously transferred good data is calculated and loaded therein. The present invention also has the capability not to transfer the last requested sector if that sector is masked. The present invention evaluates whether a stop count value equals a stop threshold value when a sector is identified as being masked. The stop count value is incremented for each sector that is read from the first storage device, regardless of whether that sector is to be transferred or masked. The stop threshold value is the total number of sectors to be transferred. If the stop count value equals the stop threshold value and the sector is masked (or not), a flag is generated to stop the transfer of that last masked sector.

摘要： The present invention is a method to minimize the firmware overhead for multi-track transfers. To this end, the present invention provides a transfer control table. The table is used to manage sector defects or other transfer adjustments. Each entry of the table contains an affected PSA and a corresponding control instruction. The control instruction includes an action such as an interrupt/branch, take no action, skip the sector or skip the following indicated sectors. The interrupt/branch bit causes an preferably when the last sector of a track has been read or written. The table is either entirely generated at the same time or is generated to provide for a track transfer. In the latter case, the remaining table entries are generated during the platter revolution or the track seek. The method provides for minimum microprocessor intervention. To that end, the microprocessor is interrupted only at the end of the multi-track transfer.

摘要： A storage target device controller (such as an embedded controller in a SCSI disk drive) processes multiple commands concurrently in accordance with the methods and structures of the present invention. Each command is stored within its own context within the target device controller to retain all unique parameters required for the processing of each command. Processing of multiple commands permits switching of command contexts within the target device to improve utilization of resources associated with the target device. For example, when a first, active, command context is prevented from further processing due to the status of the disk channel, an inactive command context may be swapped with the active command context to better utilize the host channel communication bandwidth. Similarly, a first active command context may be configured to automatically switch to a linked command context upon completion of processing to further ease management of multiple contexts. In a preferred embodiment of the present invention, a set of registers contain the active context while a second set of registers contains an inactive command context. The sets of registers are configured in such a way that the active and inactive context may be rapidly switched with no intervention by the microprocessor. The inactive register set may be read or written directly by the microprocessor, or may be automatically loaded/stored from/to a buffer memory in the target device by shifting a predetermined context structure into the inactive register set through an interface pad with the buffer memory.
摘要翻译：存储目标设备控制器（诸如SCSI盘驱动器中的嵌入式控制器）根据本发明的方法和结构同时处理多个命令。每个命令都存储在目标设备控制器内的自己的上下文中，以保留处理每个命令所需的所有唯一参数。多个命令的处理允许在目标设备内切换命令上下文以提高与目标设备相关联的资源的利用。例如，当由于磁盘信道的状态而阻止第一活动的命令上下文进一步处理时，可以利用活动命令上下文交换不活动命令上下文以更好地利用主机信道通信带宽。类似地，可以配置第一主动命令上下文以在完成处理时自动切换到链接的命令上下文，以进一步简化多个上下文的管理。在本发明的优选实施例中，一组寄存器包含活动上下文，而第二组寄存器包含非活动命令上下文。这些寄存器组被配置成使得无需微处理器干预即可快速切换主动和非活动状态。非活动寄存器组可以由微处理器直接读取或写入，或者可以通过经由具有缓冲存储器的接口板将预定上下文结构移位到非活动寄存器组中而从目标设备中的缓冲存储器中自动加载/存储到缓冲存储器。
