H.264 and VC-1 formats. The audio decoder supports multiple audio
format decoding, including MPEG-1, MPEG-2, Dolby
®
Digital, Dolby Digital+.
MPEG-4 aac and aacPlus™, WMA and WMA Pro. An integrated ARM1176
CPU with 32K Instruction and Data cache supplies over 730 Dhrystone
1.2 MIPS at 550MHz, and a high performance 667MHz 32-bit DDR-2 SDRAM
memory controller gives ample processing power for advanced applications
and future expansion capability. An additional 16-bit DDR-2 SDRAM controller
is also available for high performance applications.
The CX24501 also features an impressive array of I/O features, including
HDMI with HDCP dual USB 2.0 host controller with integrated PHYs, an
,
additional USB1.1 solution, dual integrated 10/100 Ethernet MAC with MII,
