FAT32 IP Core for NVMe Product Specification
■FAT32 IP Core for NVMe is designed to transfer data as FAT32 file system to NVMe SSD by interfacing between user logic and NVMe IP core. User transfers data to NVMe SSD as a file in FAT32 file system standard, instead of raw data. Data format in NVMe SSD after running NVMe IP reference design is raw data. So, it needs to use special software to read data from NVMe SSD as raw data when connecting SSD to other NVMe host. FAT32 file system is well known and generally used in many systems, so SSD could be read by standard tools on NVMe host.
■FAT32 IP Core for NVMe supports three commands, i.e. Format, Write file, and Read file. FAT32 IP Core supports varieties of SSD capacity (64 MB – 2 TB) with only one partition. File size to store data is adjustable (32MB - 2GB per file). Once the SSD has stored some file, file size must not be changed. Format is required to clear old file before storing the new file size in SSD.
■User interface of FAT32 IP Core for NVMe has two groups, i.e. control and data. Control interface is almost similar to dgIF typeS, but physical address and length are replaced by file number and numbers of file. Data interface of FAT32 IP Core is same as dgIF typeS interface.
■Clock domain of FAT32 IP Core for NVMe must use same domain as NVMe IP’s user clock.
●Features
■Simple user interface
