    摘要: A processor having a system on a chip (SOC) architecture comprises one or more central processing units (CPUs) comprising multiple cores. An optical Compute Express Link (CXL) communication path incorporating a logical optical CXL protocol stack path transmits and receives an optical bit stream directly after the link layer, bypassing multiple levels of the CXL protocol stack. A CXL interface controller is connected to the one or more CPUs to enable communication between the CPUs and one or more CXL devices over the optical CXL communication path.
