Signal Processing on Ambric Processor Array : Baseband processing in radio base stations

TL;DR: The aim of this thesis was to evaluate the use of parallel processor architecture in baseband signal processing by implementing three demanding algorithms in LTE on Ambric Am2000 family Massively Parallel Processor Array (MPPA).

Abstract: The advanced signal processing systems of today require extreme data throughput and low power consumption. The only way to accomplish this is to use parallel processor architecture.The aim of this thesis was to evaluate the use of parallel processor architecture in baseband signal processing. This has been done by implementing three demanding algorithms in LTE on Ambric Am2000 family Massively Parallel Processor Array (MPPA). The Ambric chip is evaluated in terms of computational performance, efficiency of the development tools, algorithm and I/O mapping.Implementations of Matrix Multiplication, FFT and Block Interleaver were performed. The implementation of algorithms shows that high level of parallelism can be achieved in MPPA especially on complex algorithms like FFT and Matrix multiplication. Different mappings of the algorithms are compared to see which best fit the architecture.
