Topic: A Survey of CORDIC-Based Processor

Digital signal processing (DSP) in VLSI technology is mainly based on parallel 
computing systems to facilitate real time implementations.  In these parallel V
LSI arrays, multiplication and accumulation (MAC) unit is used to operate basic
 arithmetic computations. However, MAC unit computing is not efficient enough w
hen the DSP algorithm includes more complicated functions, such as trigonometri
c, exponential, and logarithm.  CORDIC (COordinate Rotation DIgital Computer) i
s found as an alternative arithmetic computing algorithm to enhance the DSP per
formance.  CORDIC algorithm is implemented by a unified iterative formulation t
o evaluate these elementary functions efficiently, and the CORDIC-based process
or also resolves these computations in an iterative fashion that shares the sam
e hardware.

In this project, an amount of literatures related to "CORDIC-Based VLSI Archite
ctures for Digital Signal Processing" by Y. H. Hu will be studied to summarize 
how the CORDIC algorithm evaluate these computation tasks.  Furthermore, it wil
l include a survey of different architecture designs of the CORDIC-Based proces
sor by comparing their performances.
