Abstract
With the advent of the 2G/2.5G/3G high-speed telecommunication, the communication
system of multi-standard / multi-mode and the multi-mode in single standard has become a
trend as to offer a variety of communication services. On the one hand, DSP (Digital Signal
Processing) is often the solution to the design of communication ICs at present. The
processing speed of most DSP, however, is not fast enough to handle the great deal of
transmitted data in high-speed telecommunication systems. On the other hand, the ASIC
designs, in general, can not dynamically adjust the function of modules to maintain the
required performance. When the specifications of the system change, it will take a lot of costs
and time to redesign the IC circuits. In the project, we propose a novel architecture of
communication system to achieve the best balance between the design cost and the functions
of transceiver. This architecture is called Reconfigurable Communication Engine (RCE),
which can dynamically adjust the functions of modules to meet the altered specifications of
the system. We plan to adopt the commonly used modules in communication systems, such as
Viterbi decoder, Reed Solomon encoder/decoder, and Fast Fourier Transform (FFT) processor.
We will make a detail analysis at algorithm level to reduce the complexity. There are two
main cores in each module, including Hardcore and Softcore. The Data path is fixed in the
hardcore so that the area, processing speed, and power consumption of modules are
expectable and controllable. The conception of the reconfigurable computing is introduced in
the softcore design. According to the change of system specifications, we can dynamically
adjust the hardcore of modules by controller so as to meet the system requirement. The target
design has the property of high speed, low power consumption, scalability, and portability.
