Abstract:
Wireless communication protocols today have a computationally demanding
workload that has to be supported by mobile terminals. The need for these
terminals to be small and portable dictates a highly constrained energy
budget. Traditionally these goals were satisfied by ASIC solutions. However,
reusable hardware platforms and the need to interoperate between a wide
range of protocols has led to research into programmable hardware platforms
that can support these protocols in software. This talk will examine the
computational requirements of the wideband code division multiple access
(W-CDMA) protocol, which is one of the dominant third generation wireless
standards. Our goal is to describe computational characteristics for the
computer architect and to provide a high-level analysis of the architectural
implications. We will present a programmable architecture that takes
advantage of these characteristics. We will then show that it can be
efficiently employed on very different wireless protocols that employ
orthogonal frequency division multiplexing (OFDM) technology. OFDM is the
basis for much of WiFi and is the choice for 4G proposals. We will conclude
with remarks on a programming model for this class of domain specific
machines, and observe that it is general enough to cover a broader class of
embedded systems.
