SHIM 2.0 Update – New Version Available NOW.

After 2+ years of effort, the SHIM working group has produced SHIM 2.0. The main features of SHIM2.0 are: introduction of power related properties to enable power consumption estimation, inter-connect contention description, custom instructions description, processor functional unit description, modular XML description, vendor extension and more - all to improve performance estimation accuracy for even complex multi-manycore processors, and better reuse of SHIM XML.

Version 1.0 of SHIM (Software/Hardware Interface for Multi- and ManyCore) came out in 2015. Unlike the IEEE IP-XACT standard which defines and describes electronic components, SHIM is an architecture description standard from the software design perspective. For example, some of the architectural features that can be (directly or indirectly) described are the processor cores, the inter-core communication channels, the memory system (including hierarchy, topology, coherency, memory size, latency), the network-on-chip (NoC) and routing protocol. SHIM supports vendor-specific, non-standard architectural information for customized tools.
