Data security and privacy are major concerns for wireless
subscribers because their personal information is transmitted
over the air and is accessible to anyone. Modern wireless
communication systems address this problem by using
state-of-the-art cryptographic algorithms, such as ZUC, which
has been recently integrated into the 3GPP LTE EEA-3/EIA-3
confidentiality protection methods. In the absence of any
commercially available hardware accelerator, however, the
ZUC computational load imposes new design challenges to
the LTE layer 2 protocol stack processors in base stations; the
designer either needs to find a way to optimize the software to
offer sufficient computation power for ZUC, or add an FPGA
adjacent to the processor for acceleration. The former method
is unlikely to meet the throughput requirement, while the
latter is not cost-effective.
Together, the Xilinx®
Zynq®-7000 All Programmable SoC
(AP SoC) and Vivado® Design Suite provide a joint
hardware/software development platform that addresses
these challenges. The platform directly converts a standard’s
reference
C
code into an accelerator running in
programmable logic and an AXI interconnect to the processor
system. This new methodology facilitates hardware/software
system function partitioning for advanced performance, and
the optimized joint hardware/software design flow provides
markedly increased productivity.
