CompactTCA to combine PICMG specs

A group of communications platform and component providers have launched an initiative to define an embedded system platform specification that combines several existing CompactPCI specifications from the PCI Industrial Computer Manufacturers Group (PICMG) into a single standard.

The Compact Telecommunications Computing Architecture (CompactTCA) initiative is sponsored by a number of companies including Force Computers, Motorola Computer Group, Performance Technologies, Pigeon Point Systems, StarGen and ZNYX Networks. The group expects to propose CompactTCA as a formal PICMG activity in early Q1 2003.

The CompactTCA specification retains compatibility with most existing CompactPCI/PICMG 2.16 products and combines several CompactPCI specifications into a single standard.

The group says the proposed CompactTCA architecture complements AdvancedTCA by featuring PICMG 2.16 packet switching as the primary interconnect, mandatory system management, and elimination of the PCI bus for data transfer. The group will propose several enhancements that maintain backward compatibility with existing CompactPCI/PICMG 2.16 products. Developers would choose CompactTCA or AdvancedTCA based on application requirements, and leverage common features to migrate applications between the two platform standards.

The CompactTCA specification will also permit the use of optional auxiliary data interconnects compliant with PICMG 2.5, PICMG 2.17 and PICMG 2.20. Concurrent use of PICMG 2.15-compliant PMCs and PMC carriers will also be supported as an option.
