6. Conclusions
The use of an FPGA-based system architecture has allowed savings in both numbers of
discrete components and the space required for the control elements in the multichannel
Teletest® long range ultrasonic system. This system has a soft processor
implemented on the FPGA which has the potential for it to be reconfigured to meet the
requirements of different ultrasonic testing applications. The performance of the
multichannel ultrasonic testing system has been improved in terms of increased speed,
reduced size and reduced power consumption. Figure 8 shows the completed Teletest®
FOCUS+ prototype system and its internal assembly of the first prototype unit. This
product has been commercially successful globally since it was firstly released to the
market in May 2011 for the improvements made by the new FPGA embedded system
design over the previous system.
