What is CAPI?

OpenPOWERibm_logoIBM developed the Coherent Accelerator Processor Interface (CAPI) as a new means for solution architects to improve system-level performance.

Most FPGA Accelerators utilize PCIe as their link to the host. CAPI provides a unique alternative, allowing the FPGA accelerator to coherently attach to the fabric of a POWER8™ chip and up to 1 TB of system memory.

This new hybrid solution has a simple programming paradigm while delivering algorithm acceleration and performance well beyond what’s available today.

How is Nallatech involved?

Nallatech’s 385 card is the first supported CAPI FPGA accelerator card.

Through our membership in the OpenPOWER™ Foundation, we have collaborated with IBM and Altera to provide the OpenPOWER CAPI Developer Kit for POWER8, which includes everything needed to start developing with CAPI in a POWER8 System.

Nallatech is also working with select partners and OpenPOWER members on custom hardware and CAPI enabled solutions.
