Making Telecoms Work As at 2011 a high-end smart phone such as the LG device mentioned above and the iPad use low-power double data rate 2 (LPDDR2) mobile DRAM. This has a maximum of 8.5 Gbytes/second peak data throughput at a power consumption of 360 mW. Note this is memory power consumption not processor power consumption. Actually this is four devices housed in a package on package. The clock speed is from 100 to 533 MHz, increasing to a proposed 800 MHz for LPDDR3. Clock speeds of this order are of course running at close to the RF frequencies and therefore have to be carefully managed. There are various contenders for next-generation mobile DRAM, either evolved versions of LPDDR or alternatives promoted by vendors such as Rambus or Micron or Samsung. Samsung incidentally have almost a 50% share of this multibillion dollar market and support an option called SPMT that replaces the traditional 32 data lane technology with a four-channel, 128- lane technology that enables a total of 512 I/Os with a total bandwidth of 12 Gbytes with a target consumption of 500 mW by 2013. The average DRAM content is a smart phone or tablet is heading towards a gigabyte. A PC hosts about 3.5 Gbytes but a lot more smart phones now get shipped every year than PCs and people don't keep them as long. Also, mobile DRAM costs two to four times more than a PC DRAM because of the more stringent size and power demands. A high-end applications processor such as Qualcomm's Snapdragon APQ8064 is claimed to realise speeds of up to 2.5 GHz per core and is available in single-, dual- and quadcore versions. Drifting back through old RTT technology topics unearthed a study of media processor capabilities in 2004. Back then an application processor was considered to be a media pro- cessor with a Java hardware accelerator. The processor supported media-related applications like gaming, 3D processing, authentication and the housekeeping needed for J2ME personal profiles and MIDP (mobile information device profiles). Most of these devices were ARM ba
