A hardware VLSI implementation of a design will likely run faster than a software DSP implementation of the same design. However the hardware VLSI implementation will usually be more expensive to build and difficult to change if errors are found or the specifications change, so if the speed of a software DSP implementation is adequate the hardware VLSI implementation might impose too much risk on the project.
You may need to do a tradeoffs analysis to determine which is the best in your situation.
VLSI abbreviates to Very Large Scale Integration. VLSI is a chip design flow, to design Integrated circuits or IC chips. The chip in the mobile phone will enable functionality like Digital Signal Processing[DSP], Base band processing, Security, communication protocols like GSM/CDMA ...

Earlier, signal processing was mainly dealt with MATLAB and Simulink. DSP processors were used to process those signals. But now, VLSI platform such as FPGA and CPLD are used for the same purpose. Design and implementation of signal processing on FPGAs and CPLDs is the latest research in VLSI signal processing. Even in this domain, speech processing is mainly researched now.
