Cellular-phone market spawns new GPS chip sets

摘要

San Jose, Calif. ― Sirf Technol-ogy Inc. is rolling out three derivatives of its global-positioning satellite chip set, claiming the market will grow dramatically starting later this year as some mainstream cell phone makers begin designing handsets with integrated GPS. Sirf has respun its SirfStarIIe chip set in an 0.18-micron process to create the SirfStar-IIe/LP. It is also offering a simplified version of the chip set that off-loads navigation processing to a host CPU and another version that makes its GPS signal-acquisition technology available as a block that can be integrated with a host processor.
