Figure 1 shows DiskOnChip IDE Pro operation from the system level, including the major hardware
blocks.
DiskOnChip IDE Pro integrates an IDE controller and flash devices. Communication with the host
occurs through the host interface, using the standard ATA protocol. Communication with the flash
device(s) occurs through the flash interface.
The IDE controller incorporates a Control & Status block that consists of the Command Block
registers. The ATA commands that instruct the IDE controller which operation needs to be executed
are written/read from the Command Block registers. The data blocks are also transferred via the
Command Block Registers. A description of the Command Block registers can be found in
Section 4.
The embedded EDC/ECC mechanism is based on the Hamming code algorithm, and can detect up
to 2 bits and correct 1 bit per 512 bytes.
