Abstract

The invention provides a cache manager and a control component. The cache manager comprises an interface, a allocation module and a memory, and the interface receives a cache distribution request and sends the cache distribution request to the distribution module; and the interface receives the first cache index information returned by the allocation module and outputs the first cache index information; in response to the cache allocation request, the allocation module allocates N idle storage blocks and generates first cache index information, the storage blocks are located in a cache, N is a positive integer, and the first cache index information comprises indexes of the N storage blocks, wherein the memory stores an index of at least N memory blocks. The cache manager realized by hardware is used for replacing software management cache in the prior art, so that the number of times of interaction between the software and the hardware during cache allocation in the control component is reduced, the information interaction speed in the control component is improved, and the technical effect of reducing the time of data transmission from a host to a flash memory chip is achieved.

Description

technical field [0001] The present application relates to storage technology, in particular, to a cache manager and a control component. Background technique [0002] figure 1 A block diagram showing a solid-state storage device. The solid-state storage device 102 is coupled with the host, and is used to provide storage capacity for the host. The host and the solid-state storage device 102 can be coupled in various ways, including but not limited to SATA (Serial Advanced Technology Attachment, serial advanced technology attachment), SCSI (Small Computer System Interface, small computer system interface) , SAS (Serial Attached SCSI, serial connection SCSI), IDE (Integrated Drive Electronics, integrated drive electronics), USB (Universal Serial Bus, universal serial bus), PCIE (Peripheral Component Interconnect Express, PCIe, high-speed peripheral component interconnection), NVMe (NVM Express, high-speed non-volatile storage), Ethernet, Fiber Channel, wireless communication...
