SOM Overview
Jacinto 7 System On Module
Features
According to Texas Instruments website, Jacinto 7 SOM has the following features:
- TDA4VM/DRA829V (J721 E) processor
- Optimized power solution (PMIC)
- DRAM, LPDDR4‐3733, 4GByte total memory, support inline ECC
- Octal‐SPI NOR flash, 512Mb memory (8bit)
- HyperFlash + HyerRAM, 512Mb flash memory + 256Mb RAM
Also, it is important to mention that TDA4VM and DRA829V processors heterogeneous architecture includes:
- A mix of fixed and floating-point DSP cores
- Arm® Cortex®-A72 cores
- Matrix math acceleration for machine learning
- Integrated ISP and vision processing acceleration
- 2D and 3D GPU cores
- H.264 encode/H.265 decode acceleration
