The System IP from Akeana encompasses a suite of component blocks designed to expedite processor system development. This suite includes a Compute Coherence Block (CCB), which integrates clusters of up to eight cores using a directory-based protocol. Along with shared cache memory, the CCB interfaces with both coherent (AMBA CHI) and non-coherent (AMBA AXI) interconnect fabrics, offering a localized coherence domain. The IP also features an Input-Output Memory Management Unit (IOMMU) and an Advanced Interrupt Architecture. These components allow for robust system customization, making Akeana an ideal partner for companies seeking scalable and flexible solutions. The non-coherent interconnect fabric facilitates a streamlined multi-core system architecture, while the AkeanaMesh, a coherent interconnect fabric, supports large-scale many-core configurations, enhancing performance, reliability, and system integration capabilities.
