The Outstanding AVR based SCSI RAM Disk

Have you ever heard about the SCSI before? If you haven’t, then you should hang out here and read on the article…

For your information, SCSI is the short acronym for “Small Computer System Interface”, where it is a set of standards for physically connecting and transferring data between computers and peripheral devices. Technically, the SCSI standards are for defining commands, protocols, electrical and optical interfaces.

Although SCSI is mostly being used for hard disks and tape drives, but it can also connect to a wide range of other devices, such as scanners and CD drives. Normally, the SCSI standard defines command sets for specific peripheral device types.

SCSI can be acted as different interfaces, which as: Intelligent interface – it can hide the complexity of physical format. Peripheral interface – it enables up to 8 or 16 devices to be attached to a single bus. Buffered interface – it uses handshake signals between devices, SCSI-1, SCSI-2 have the option of parity error checking. Peer to peer interface – the SCSI protocol will define communication, either from host to host, host to a peripheral device or peripheral device to a peripheral device. The main goal of this project is to develop a universal SCSI controller that consisting of standard parts and it would be better than any other ram disk, once you’ve done with it!
