Overview
mDOC H3 consists of the following major functional blocks, as shown in Figure 6.
Figure 6: Simplified Block Diagram
These components are described briefly below and in more detail in the following sections.
Host IF – Host physical interface block. Includes the following interfaces: Demux
(Standard), Multiplexed, and Serial.
Host Agent – Logical host interface supporting the host protocol and Programmable
Boot Block with XIP functionality.
Flash Partition Management – High level management of the Flash media,
managing flash logical partitions, and their attributes.
Flash BD Management – Management of the Flash media at a Block Device level,
primarily performing logical to physical address translation.
Boot Agent – Management of host boot sequence – Loading of Boot code from flash
media upon power up.
ECC / EDC - Error Detection and Error Correction Codes (EDC/ECC) - On-the-fly
Flash error handling.
Data Buffer – 4KB Dual-Port RAM memory, used as a pipeline buffer, for enhanced
data transfer rate.
Flash Agent – Provides High level Flash management functions and sequences for
Flash control and error condition handling.
