Board

Pandora PCB rev 5

The Pandora is based upon the Beagle Board layout. It bases upon a OMAP3530 System-on-a-chip, that includes a whole family of processors in one single chip:

• ARM Cortex-A8 CPU
• PowerVR SGX graphics core
• C64x+ DSP core

OMAP3530

• OMAP35x: Main page on TI site[1]
• OMAP3530 specific page[2] This lists the features of the chip and has all the applicable Technical Documents
• OMAP35XX technical manual: [3] (38MB PDF)

Other OMAP3530 Projects

• Always Innovating Touch Book[4]
• Beagle Board Resources[5] As it uses the same SoC, many BB resources are also relevant for the Pandora.
• Beagle Board Google Group[6]

Cortex-A8

This processor is part of the ARM risc cpu family[7] that is licensed by a lot of hardware vendors. It has multiple command extensions as NEON (similar to MMX for x86 architecture)

• r1p1[8] Note: OMAP3530 uses rev1p2
• UPDATE: r2p2 Documentation [9] Note: OMAP3530 uses rev1p2
• NEON instruction set [10]
• NEON memory hazards[11]

PowerVR

• Official site[12]
• OpenGL ES

C64x+

Digital signal processors allow to do complex calculations within only a few cycles
