FAT32 IP Core for SATA Product Specification
■FAT32 IP Core for SATA is designed to transfer data as FAT32 file system to SATA device. by interfacing between user logic and SATA Host IP Core suite. User can transfer data to SATA device as a file in FAT32 file system standard instead of raw data. In general system, data format in SATA device when using SATA Host IP Core suite is raw data. When user connects SATA device to other systems, it needs to use special software to access as raw data. FAT32 file system is well known and general use in many systems, so user can read data from SATA device without special software.
■FAT32 IP Core for SATA supports three commands, i.e. Format, Write file, and Read file. FAT32 IP Core can work with varieties of disk capacity from 64 MB – 2 TB with only one partition, stored data as a file with adjustable file size from 32MB - 2GB per file. Once a disk is writtten, file size cannont be changed until it is formatted.
■User interface of FAT32 IP Core for SATA 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 dgIF typeS interface.
■Clock domain for FAT32 IP Core for SATA is same as SATA Host IP’s user clock.
●Features
■ Simple user interface
