Device, system, and method for hardware small computer system interface

A system (101) comprising:

• a slave controller (104);
• and
• a small computer system interface (SCSI) device (102) comprising:
• an initialization unit (110) configured to (i) send a first signal to the slave controller (104), (ii) receive, from the slave controller (104), first information associated with a peripheral device (106) in response to the first signal, wherein the first information comprising a status of a connection of the peripheral device (106) with the slave controller (104), a block size of the peripheral device (106), and specifications of the peripheral device (106), (iii) receive, second information from the master controller (108), wherein the second information comprising a direction of the transfer of the data, a logical bit address of the master controller (108), and a size of the data to be transferred;
• and
• a control unit (112) that is coupled to the initialization unit (110), and configured to (i) generate a plurality of command descriptor blocks (CDBs) based on the first information and the second information, and (ii) send the plurality of CDBs to the slave controller (104) for a transfer of data between the master controller (108) and the peripheral device (106), and (iii) transfer the data between the master controller (108) and the peripheral device (106);
• wherein, the initialization unit (110) and the control unit (112) are implemented on at least one of, a Field Programmable Gate Array (FPGA) and Application Specific Integrated Circuits (ASICs).

A method (300) comprising:

• sending, by way of an initialization unit (110) of a small computer system interface (SCSI) device (102), a first signal to a slave controller (104);
• receiving, by way of the initialization unit (110) of the SCSI device (102), first information of a peripheral device (106) from the slave controller (104), wherein the first information comprising a status of a connection of the peripheral device (106) with the slave controller (104), a block size of the peripheral device (106), and specifications of the peripheral device (106);
• receiving, by way of the initialization unit (110) of the SCSI device (102), second information from a master controller (108), wherein the second information comprising a direction of the transfer of the data, a logical bit address of the master controller (108), and a size of the data to be transferred;
• generating, by way of a control unit (112) of the SCSI device (102) that is coupled to the initialization unit (110), a plurality of command descriptor blocks (CDBs) based on the first information and the second information;
• and
• sending, by way of the control unit (112) of the SCSI device (102), the plurality of CDBs to the slave controller (104) for transfer of the data between the master controller (108) and the peripheral device (106);
• and
• transferring, by way of the control unit (112) of the SCSI device (102), the data between the master controller (108) and the peripheral device (106);
• wherein, the initialization unit (110), and the control unit (112) are implemented on at least one of, a Field Programmable Gate Array (FPGA) and Application Specific Integrated Circuits (ASICs).
