Abstract
A data storage device includes a storage memory device, a control unit suitable for generating a descriptor, which describes a work for controlling the storage memory device, and storing the descriptor in a working memory, and a memory control unit suitable for generating control signals for the storage memory device by fetching an instruction set from an instruction memory based on the descriptor.
Claims20
A data storage device comprising:
- a storage memory device;
- a control unit suitable for generating a descriptor, which describes a work for controlling the storage memory device, and storing the descriptor in a working memory;
- and
- a memory control unit suitable for generating control signals for the storage memory device by fetching an instruction set from an instruction memory based on the descriptor.
1 more element
A memory control unit comprising:
- a descriptor fetch block suitable for reading a descriptor from a working memory;
- an instruction fetch block suitable for fetching an instruction set from an instruction memory based on the descriptor;
- and
- an instruction push block suitable for providing the instruction set and a descriptor parameter corresponding to the instruction set to a signal generation block in order to generate control signals for a storage memory device based on the instruction set and the descriptor parameter.
1 more element
A memory control unit comprising:
- a direct memory access (DMA) block suitable for reading descriptor and data from a working memory;
- a descriptor queue suitable for storing a descriptor ID corresponding to the descriptor;
- a descriptor fetch part suitable for generating a descriptor address based on the descriptor ID for the DMA block to read the descriptor based on the descriptor address;
- an instruction fetch part suitable for fetching an instruction set from an instruction memory based on an address of the instruction memory, which is included in the descriptor;
- and
- an instruction push part suitable for providing the instruction set and a parameter of the descriptor to a signal generation block, and requesting the DMA block to process data stored in the control memory or data to be stored in the working memory based on the address of the descriptor.
