摘要：
This paper presents the architecture and implementation of LMAC which is the core block for high speed modem such as HSPA+ and LTE. The required data rate of these modems are 28.8Mbps/11.5Mbps (HSPA Release 7 modem) and 100Mbps/50Mbps (LTE modem) for downlink/uplink, respectively. To support higher data rate, we designed the new LMAC. Architecturally, LMAC includes cipher HW and provides functions such as fast data transfer, packet generation and parsing. Especially, we designed a new function which combines data transfer with cipher and has more performance benefit. As a result, our design can be used for the platform to support HSPA+ & LTE modems. And also, we reduced the processing time and the CPU & bus utilization, therefore, SW can obtain more margin to process the protocol stack.
