QUALCOMM Samples Dual-CPU EV-DO Rev A Chip

QUALCOMM has begun sampling of its new dual-CPU Convergence Platform chip aimed at a new generation of consumer devices for CDMA2000 1xEV-DO Revision A networks. QUALCOMM MSM7500 chipset is designed form personal multimedia devices ranging from high-end PDAs and Smartphones to wireless computers to portable video players, music centers, gaming consoles, etc.


QUALCOMM said the chip offers the processing capacity needed for capabilities such as an 8.0 megapixel digital camera, camcorder-like video recorder, VGA resolution gaming, and support for major audio and video formats. The chip design integrates an ARM11 applications processor and an ARM9 modem processor. It supports QUALCOMM's Launchpad suite of advanced multimedia, connectivity, position location, user interface and removable storage functionality, and QUALCOMM's BREW solution, which enables the download and monetization of advanced applications and content. http://www.qualcomm.com

  • CDMA2000 1xEV-DO Rev. A is optimized for packet data service, offering peak data rates of up to 3.1 Mbps on the forward link and up to 1.8 Mbps on the reverse link. It also supports QoS for delay-sensitive applications, including a variety of IP-based services such as VoIP and real-time conversational services such as push to talk, video telephony, low-delay gaming and "instant multimedia" (an extension of push to talk that combines immediate voice with simultaneous delivery of video and pictures). Another key attribute is support for 1xEV-DO Gold Multicast, which would enable the delivery of high-quality video and audio to a large number of users simultaneously. If standards progress permits, Qualcomm's MSM6800 chipset will also support 1xEV-DO Platinum Multicast.


  • In April 2005, QUALCOMM began sampling first chipset for CDMA2000 1xEV-DO Revision A.
