The deal extends Samsung’s pre-existing partnership with CSR, which is the main supplier of the GPS technologies found in its Galaxy S smartphones. Specifically, Samsung uses CSR's SiRFstarIV offering, a mobile tracking technology that can be used for both indoor and outdoor navigation.

Samsung's semiconductor unit has a history in the mobile market, most notably with its Exynos line of processors used in its Galaxy smartphones. In April, the Korean tech giant launched its latest Exynos 4 quad-core chip, said to reach speeds up to 1.4GHz and consume 20 percent less power than prior-generation Exynos processors.

Apart from its own line of smartphones, Samsung's mobile processors, which are based on the low-power architectures of U.K.-based chip licensor ARM, also are used in Apple's iPhone.

With its acquisition of CSR's mobile division, Samsung said it stands to broaden its existing processor portfolio and compete more aggressively against other smartphone chip makers, such as Qualcomm and Texas Instruments.

"This strategic partnership combines Samsung's world-class semiconductor technology with CSR's cutting-edge wireless connectivity and location expertise," said Stephen Woo, president of System LSI Business, Device Solutions, Samsung Electronics, in a statement. "By leveraging CSR's R&D capability, Samsung will strengthen its application processor platform and solidify its position as a leading semiconductor solutions provider."

Joep van Beurden, CEO of CSR, said the agreement with Samsung will help CSR evolve into a competitive and "higher-gross-margin platform" company in the mobile chip market.

"I believe that under Samsung's ownership the handset operations will be in a better position to prosper in the global handset market," van Beurden said in a statement.
