Greg Turetzky from SiRF Technology/CSR Group
April 8, 2010 By: Alan CameronGreg Turetzky, senior marketing director for SiRF Technology Inc., a member of the CSR Group of companies, discusses changes in GPS boards between 1995 and now.
Moore's Law is discriminatory. Overall power consumption should have come down by a factor of 128 over seven cycles of Moore's Law during the 15 years since 1995, and this is largely so. Similarly for the area of the digital silicon. However, the RF side of Moore's Law has not kept pace. There are fewer external components, but the amount of silicon reduction, or silicon capability, now takes up about half the area. Further, the software has moved in the opposite direction.
The value being added every year into a GPS receiver is mostly coming from software.
