Kilocore was a family of 8-bit MPPA microprocessors designed by Rapport introduced in 2006 that implemented their "KiloCore Architecture Computing Fabric", a scalable many-core architecture.

Architecture

Kilocore architecture is based on leased technology from the PipeRench Project from Carnegie Mellon.

Members

The first model of the Kilocore family was the KC256 which made a debut at the 2006 CES. This model incorporated 256 cores in a grid of 16 strips of 16 cores each. In 2006 IBM announced a joint collaboration with Rapport to produce 2 additional models: KC1024 and KC1025. The 1024 model was supposed to be roughly the design of KC256 times 4. The 1025 model is the same as the 1024 model with an additional IBM Power PC CPU core incorporated as well for general-purpose tasks. These two models appear to have never made it to market before Rapport was dissolved in 2009.
