1 F1 f9 g2 |6 c1 \* M k9 f# O1 NThe 20K2 digital audio processor is based on the 20K1 architecture and accelerates OpenAL 3D audio, X-Fi CMSS-3D, X-Fi Crystalizer and other advanced X-Fi audio processing. The 20K2 uses an advanced PCI Express (PCIe) one-lane interface and adds an embedded RISC processor to safeguard against control latencies introduced by the PCIe interface. The 20K2 also expands the audio I/O capabilities and upgrades the SDRAM interface to DDR for increased local memory bandwidth. In addition, The 20K2 incorporates a High Definition audio architecture (UAA) component." k9 Z) k+ ~, }) r
