The board with the CPU, GPU, RAM, and eMMC memory which detaches from the Mainboard. Depending on various commercial and technical considerations, new CPU boards may become available to upgrade existing Pyras.
CPU
Main Article: CPU
The OMAP5 (OMAP5432) is the SoC (System on Chip) of the Pyra. It's designed by Texas Instruments and fabricated by UMC on their 28LP process. It resides on the CPU-Board, with these specifications:
- 2x ARM Cortex-A15 @ 1.5Ghz with NEON SIMD
- 2x ARM Cortex-M4
GPU
Main Article: GPU
This is on the CPU-Board, as part of the OMAP5 SoC, so has a chance of being upgraded in the future but it cannot be changed separately to the CPU. Unlike a discrete GPU, each block reads/writes main system memory and final video output is done by the TI DISPC display controller block.
- PowerVR SGX SGX544-MP2
- Vivante GC320 2D Accelerator
- HDMI Encoder: HDMI 1.4a, HDCP 1.4, and DVI 1.0 Compliant" [1]
RAM
Main Article: RAM
Dual Channel PC DDR3L 532MHz:
eMMC
See also: Storage
32GB of eMMC storage is also on the CPU Board.
Connection between boards
The CPU board is connected to the other board using two low profile inline connectors that are officially known as:
- Hirose DF40C-100DP-0.4V(51) - 2x Board to Board & Mezzanine Connectors 100P SMT HEADER NO FITTING, NO BOSS
