Next to the battery connection we find that engineers set aside a corner of the welding cited 10-bit, speculated that the reserved bits should be a FM chip bonding.

P7 board all the electronic components are all here, and looks at a glance, the biggest piece of silicon that is TCC8901, and next to two Samsung cache, all use FBGA package.

That piece of chip Samsung's DDR2-800 SDRAM, chip capacity 1Gb (128MB), 8Banks structure, FBGA package. That piece of chip Samsung's DDR2-800 SDRAM, chip capacity 1Gb (128MB), 8Banks structure, FBGA package. A chip capacity of 128MB, 2 is 256MB, ensure the smooth 1080P Full HD video playback.

TCC8901 built-in 16KB instruction cache and 16KB data cache, an integrated MMU management unit (Memory Management Unit, it is the central processing unit (CPU) used to manage virtual memory, physical memory control circuit, is also responsible for virtual address mapped to physical address, as well as provide hardware mechanisms for memory access authorization).

TCC8901 support for video hardware decoding, encoding, including MJPEG, MPEG-1, MPEG-2, MPEG-4 SP, MPEG-4 ASP, MPEG-4 AVC (H. 264), DivX, H.263, WMV9, VC-1, RV, with 2D/3D graphics acceleration engine, as well as the Overlay Mixer, can output fluid 1080P Full HD video images.

TCC8901 internal integrated high-speed USB 2.0 OTG controller, HDMI controller, as well as a 10bit DAC, supports NTSC or PAL video output mixed output (specifications NTSC-M/4.43, PAL-B/D/G/H/I/M/N / Combination N).

WM8988L and the bandwidth between the ARM is definitely not as good as the built-in 10bit DAC and the bandwidth between ARM, taking into account the data transfer full HD video the higher requirements, and users to watch video when the lower quality requirements, so guess TCC8901 the built-in 10bit DAC should be specifically for the video but the audio conversion prepared.
