AVE-File™ (File System)

Overview

AVE-File is a file system that enables storage of data programs on portable information machines, household electrical appliances, and OA appliances. The file system is complaint with the Windows standards for FAT12/16/32, VFAT, and DOS partitioning and enables data exchange of computers and other devices. As a standard feature, AVE-File supports SD memory cards as well as Compact Flash. With the optional AVE-File Flash Memory Driver (AFMD), it can support NORtype internal flash memory. AVE-File achieves compact data program storage suitable for largescale data exchange and portable systems.

• Supports multi-tasking:
  No need for OS in single-task applications.
• Confugurable file system building
• FAT file system checking function
• Logical file system /media information acquisition function.
• Sample physical storage device drivers:
  CompactFlash . ATA disks, Windows NT 4.0/2000 disks
• Sample logical file systems: ROM-based simulated file system, Win32 file system
• Command interpreter bundled for confirming operations
• Operation guaranteed on Hitachi SH-3 Solution Engine (MS7709ASE01) / More v4.0 and Win32 environments

AVE-File SDK Development Kit

The AVE-File SDK is a porting package that offers full source code and includes a PC-based application development environment, a wide range of sample drivers, a test program and documentation. Guaranteed operation using the Hitachi SH-3 Solution Engine (MS7709ASE01) under the More v4.0 and Windows NT 4.0/2000 environments facilitates porting to different platforms and devices. Development work can be started before the hardware is available because applications developed on a PC using VC++ can easily be recompiled to run on the target platform.
