SiRF have announced their latest platform, SiRFatlasIV, a chipset which bundles one of the company’s GPS receivers with a multimedia processor. Intended to be used in mobile devices, the chipset offers both the same 64-channel location system as in their standalone SiRFprima receiver, and a 500MHz ARM11 processor for application and video crunching.The SiRFatlasIV has a hardware video post-processing accelerator for T-DMB-DVB-H and CMMB, among other things, together with an integrated NAND and SD controller. Meanwhile a high-sensitivity GPS core means that smaller antennas can be used, again keeping end-device size down and prices cheap.
To that end, the SiRFatlasIV also has a touchscreen controller, 10-bit ADC, video input and USB 2.0 PHY. SiRF’s new chipset has been picked up by ASUS, Foxconn, Navigon, Wistron and Nextar, among others, and is used in the Navigon 3300 max, Nextar Q4-MD and YF International 82A, among other products.
