To connect a logical partition to an HEA, you must create a logical HEA (LHEA).
This allows these logical partitions to access external networks through the HEA without having to go through an Ethernet bridge on another logical partition. Multiple logical partitions can connect directly to the HEA and use the HEA resources. 16.2.1.1 Host Ethernet adapterĪn HEA is a physical Ethernet adapter that is integrated directly into the GX+ bus on a managed system. Using Shared Ethernet Adapter technology, logical partitions can communicate with other systems outside the hardware unit without assigning physical Ethernet slots to the logical partitions.

Virtual Ethernet technology facilitates IP-based communication between logical partitions on the same system using VLAN-capable software switch systems. The key virtual networking components in PowerVM are host Ethernet adapter (HEA), Internet Protocol version 6 (IPv6), link aggregation (or EtherChannel), shared Ethernet adapter, and VLAN. This makes it possible to apply the features available in high-level specification languages for the development of real designs.īhanu Prakash Reddy Tholeti, in Handbook of Fiber Optic Data Communication (Fourth Edition), 2013 16.2.1 PowerVM virtual networking Our aim was to develop a coherent path from this high-level specification formalisms to prototyping.

The techniques used at high-level specification (abstract specification, formal verification and refinement, testing) and at the prototype level (co-simulation and hardware-software prototyping from VHDL and C code obtained from the specification and the interface) are not new. The design flow is validated at the high-level specification level (by means of simulation and formal verification) and at the prototype level (by means of cosimulation and by running the obtained prototype on the prototype board). Our design flow is composed of three different phases corresponding to three abstraction levels (high-level specification, hardware and software specification, prototyping). The speedup and performance results that we have presented prove the feasibility of the proposed approach. A worked example, the Ethernet bridge served to illustrate the proposed design flow. The design flow allows us to build a hardware-software prototype from an initial abstract specification written in LOTOS. In this paper, we have presented a complete design flow for hardware-software co-design based on LOTOS. WOLFGANG ROSENSTIEL, in Readings in Hardware/Software Co-Design, 2002 8 Conclusions
