DM814x - DIDO

Processor:  Texas Instruments "DaVinci" DM814x

DIDO is a ready-to-use CPU module based on Texas Instruments DM8148 high performance application processor. DIDO is the first product of DAVE Embedded Systems' Ultra Line, which includes best-in-class solutions and full featured SOMs. In particular, for DIDO this means a boost on performances, thanks to the 2 GB DDR3 @ 533 MHz SDRAM memory, and great versatility thanks to the integrated PCI Express interface. DIDO is designed to be easily included in customer's embedded systems, due to the small form factor, the inexpensive stacking connectors and the back-compatibility with DAVE's NAON CPU module.

Main Features

  • Top class CPU module based on Texas Instruments DM814x processors family
  • Ultra Line - ARM Cortex-A8 architecture @ 1 GHz
  • Up to 2 GB DDR3 @ 533 MHz SDRAM
  • HD Video Encoding/Decoding Capabilities (HDVCIP)
  • DSP engine (available on DM8148)
  • NEON Multimedia Coprocessor and PowerVR® SGX Graphics Engine
  • Small form factor
  • Rich interfaces set including PCIe, dual CAN, Ethernet, SATA and native 3.3V I/O
  • Naon pinout compatible
  • Evaluation Board available with exhaustive Development Kit
