DIDO Texas Instruments DM814x/AM387x CPU module[edit | edit source]

Dido 02.png

DIDO is a ready-to-use CPU module family based on Texas Instruments DM814x (DaVinci) and AM387x (Sitara) Cortex-A8 high performance application processors. DIDO is the first product of DAVE Embedded Systems Ultra Line, which includes best-in-class solutions and full featured SOMs. DIDO shares the same DM814x processor with Maya (Lite Line) and Naon (Esatta Line) and is built with the same connectors format (ZFF) as Naon and Lizard (Esatta Line).

Dido is a family of system-on-modules that belongs to DAVE Embedded Systems Ultra Line product class.

It is based on Texas Instruments DaVinci digital media processor DM814x. Dido Hardware Manual provides detailed information about hardware interfaces and characteristics. This document will provide a functional overview of the module and will focus on system-related issues.
