Flash interface controller and operation command processing method

An operation command processing method, applied to a flash interface controller, wherein the flash interface controller comprises:

• a channel management module, a channel, a command buffering management module, a data buffering management module, a non-linear (NAND) config storage (NCS) memory, and a programmable timing generator (PTG) memory, and the channel comprises a die concurrent schedule (DCS) module, a flash access agent (FAA) module, a (PTG) module, and a physical layer interface module, and the method comprises:
• allocating, by the channel management module based on a channel number in a received operation command, the operation command to a channel corresponding to the channel number;
• storing, by the DCS module in the channel, the received operation command to the command buffering management module;
• and sending a scheduled operation command in the received operation commands to the FAA module;
• obtaining, by the FAA module, a command parameter of the operation command from the command buffering management module after receiving the operation command;
• reading, based on a NAND config storage NCS memory location indicated by the command parameter, first type microcode starting from the NCS memory location in the NCS memory, and executing the first type microcode;
• and sending an index command obtained after executing the first type microcode to the PTG module;
• reading, by the PTG module, second type microcode from a location that corresponds to the index command and that is in the PTG memory, and executing the second type microcode;
• and sending a flash bus operation obtained after executing the second type microcode to the physical layer interface module;
• and
• sending, by the physical layer interface module, the flash bus operation to a flash bus.

A computer-readable storage medium, wherein the storage medium stores at least one instruction, and the instruction is loaded by a flash interface controller and is configured to perform an operation command processing method which is applied to a flash interface controller, wherein the flash interface controller comprises:

• a channel management module, a channel, a command buffering management module, a data buffering management module, a non-linear (NAND) config storage (NCS) memory, and a programmable timing generator (PTG) memory, and the channel comprises a die concurrent schedule (DCS) module, a flash access agent (FAA) module, a (PTG) module, and a physical layer interface module, and the method comprises:
• allocating, by the channel management module based on a channel number in a received operation command, the operation command to a channel corresponding to the channel number;
• storing, by the DCS module in the channel, the received operation command to the command buffering management module;
• and sending a scheduled operation command in the received operation commands to the FAA module;
• obtaining, by the FAA module, a command parameter of the operation command from the command buffering management module after receiving the operation command;
• reading, based on a NAND config storage NCS memory location indicated by the command parameter, first type microcode starting from the NCS memory location in the NCS memory, and executing the first type microcode;
• and sending an index command obtained after executing the first type microcode to the PTG module;
• reading, by the PTG module, second type microcode from a location that corresponds to the index command and that is in the PTG memory, and executing the second type microcode;
• and sending a flash bus operation obtained after executing the second type microcode to the physical layer interface module;
• and
• sending, by the physical layer interface module, the flash bus operation to a flash bus.
