ARM is forecast to maintain its position as the leading architecture for 32-bit embedded processors in the automotive sector in 2009, ahead of Power Architecture, according findings from Semicast's Embedded Processing Service.
ARM is estimated to have overtaken Power Architecture as the leading 32-bit architecture in the automotive sector in 2008. Semicast judges that ARM will maintain its lead in 2009 and then consolidate its position in 2010 and over the medium term, with a growth rate of 16%. In comparison, the growth rate for Power Architecture is forecast to be 5%.
Power Architecture was introduced to the automotive sector almost 10 years ago, following the announcement from Motorola (now Freescale) of the MPC5xx family as a replacement for 68K in powertrain control. Today Power Architecture is established as one of the leading 32-bit architectures in powertrain, particularly in North America, although it faces strong competition from SuperH (Renesas) and V850 (NEC).
In contrast, ARM's presence in the automotive sector has developed in areas other than powertrain and today it is established in multiple systems across the vehicle, including airbag, body electronics, electronic braking, instrument clusters, infotainment and embedded navigation systems. Semicast says this diverse application base is the key factor behind the higher revenue growth forecast for ARM over Power Architecture in the automotive sector, as a wide range of suppliers work together to drive forward ARM in the vehicle.
