The board with the CPU, GPU and RAM 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.
