PICMG has adopted the AMC.4 specification, which adds RapidIO interconnects to the company's AdvancedMC (Advanced Mezzanine Card) family. RapidIO is suitable for embedded industry's intra-system interconnects. The architecture is a high-performance packet-switched, serial technology that is used in the signal processing, networking, and communications markets.
The new specification is a subsidiary to the company's AMC.0 specification that defines the mechanical, interconnect, management, power and thermal requirements for the industry standard mezzanine. The new specification defines RapidIO implementations on AdvancedMC and helps support PICMG 3.5, which defines RapidIO on AdvancedTCA modes. The new specification includes standard implementation guidance for specific configurations such as 1x and 4x RapidIO.
