Transparent, reliable, high performance interprocess communications services for distributed systems.
Enea LINX provides reliable, high-performance, interprocess communications services that make complex distributed systems easier to conceptualize, model, partition, and scale. Utilizing direct message passing, LINX is the only IPC technology that scales from DSPs and microcontrollers to 64-bit CPUs. LINX supports any distributed system topology, from a single processor on a single blade, to large networks with complex cluster topologies deployed on hundreds of processors in a multi-rack system.
- Transparent, system-wide interprocess communications service
- Connects applications running on different operating systems in a seamless fashion using high-performance direct message passing
- Scales from high-end CPUs to DSPs, and from single processor systems to large distributed systems with arbitrary cluster topology.

Transparent, Scalable IPC Services
LINX enable application processes distributed across multiple operating systems, CPUs, and interconnects to communicate in a seamless fashion, as if they were running on the same CPU under the same operating system. LINX provides the same services to the application regardless of hardware, operating system, physical interconnect, and network topology. This consistency and transparency makes distributed applications easy to partition and develop, enables them to be reconfigured and scaled with minimal changes to the application code. It also increases overall system availability and makes systems easier to debug and maintain over time.
High-Performance, System-Wide IPC Solution
LINX provides a system-wide, high-performance IPC solution that eliminates the need to use multiple IPC services in the same system. Utilizing a high-performance, lightweight, direct messaging passing technology, LINX provides the performance and versatility needed to satisfy local and remote IPC requirements across all CPU (including multi-core devices), OS, and interconnect boundaries. LINX can even act as a transport for bearer protocols such as UDP and TCP, and is efficient enough to work with DSPs.
More Scalable than TIPC and TCP/UDP/Sockets
LINX utilizes an innovative address map for connections that greatly enhances flexibility and scalability. Unlike competitive IPC models, which must maintain the entire system address map on every node in the system, LINX nodes store only the addresses needed for active connections.

AMCC will deliver Enea's open source LINX interprocess communications services with its new PPC 460GT-based Arches AdvancedMC reference design kit.
LINX Supports a wide range of Freescale processors.

As a result, they require very little memory for code/data storage, and can be easily reconfigured. This enables LINX systems to scale to very large networks with complex cluster topologies (i.e., clusters connected by bridges and gateways), including those containing small-footprint DSP and microcontroller nodes.
High Reliability and Availability
LINX enhances distributed system availability by providing supervision and failure reporting for designated connections, both for physical CPU interconnects and logical connections between endpoints.
