In 5G applications, the most compute-intensive workload is FEC processing on the physical layer (L1) of the RAN architecture. Its main function is to correct information errors caused by noise or interference during the transmission of communication signals, help improve network performance and reduce network costs. FEC is also a general function and can be implemented across different software vRAN vendors. In addition, FEC accelerated processing does not include cell state information, allowing it to be easily virtualized, providing the benefits of resource sharing and simplifying base station migration.
ADLINK’s PCIe-ACC100 is a PCIe interface accelerator adapter developed based on the Intel's vRAN Dedicated Accelerator ACC100 eASIC chip. It supports 4G and 5G codec acceleration, checksum rate matching, onboard 4G ECC memory, and hybrid automatic repeat request technology (HARQ). The PCIe form factor HHHL (half-height, half-length) can meet the needs of most application scenarios.
