US 10,482,054 B1 · AXI-CAPI adapter

Abstract

The coherent accelerator processor interface (CAPI) provides a high-performance when using heterogeneous compute architectures, but CAPI is not compatible with the advanced extensible interface (AXI) which is used by many accelerators. The examples herein describe an AXI-CAPI adapter (e.g., a hardware architecture) that converts AXI signals to CAPI signals and vice versus. In one example, the AXI-CAPI adapter includes four modules: a low-level shim, a high-level shim, an AXI full module, and an AXI Lite module which are organized in a hierarchy of hardware elements. Each of the modules outputs can output a different version of the AXI signals using the hierarchical structure.

Dependent claims

An Advanced eXtensible Interface (AXI) to coherent accelerator processor interface (CAPI) adapter, comprising:

a first signal interface configured to transfer CAPI signals between the adapter and a power service layer (PSL);
a second signal interface configured to transfer AXI signals between the adapter and an AXI-compatible accelerator;
and
a hierarchy of hardware elements configured to convert the CAPI signals to at least two different types of AXI signals.
