Thanks Dr DSP for your comment, To quickly answer your question, FPGA enables more technical performance while IP allows costs and time-to-market reductions for motor control applications compared to microcontrollers. Hereís the explanation below. Yes, microcontroller single chip solutions are great to implement motor control functions in a system. However, they offer limited options to an ever evolving and complex application that is motor control. Many technical limitations of microcontroller chip can be overcome by FPGA because of hardware acceleration, parallelization and increased HW/SW flexibility. To get the FPGA pitch, Iíd invite you to read the article about FPGA-based motor control in the latest issue of the Xilinx Xcell magazine: http://cde.cerosmedia.com/1N4cc1a89f283a0012.cde/page/8 (Yes, the current paper is Altera-based and the above paper is Xilinx-based but same principles apply regarding how motor control apps can be improved with FPGA technology). The above article shows technical advantages of using FPGA for motor control apps. However, in the real world, the motor control designer doesnít necessarily know about FPGA neither about how to design advanced motor control features by leveraging FPGA technology. Hence, the way for him/her to actually benefit of FPGA advantages while also achieving compelling costs and time-to-market reduction, is to use third-party IP in its design. More on this topic on my blog post : http://www.design-reuse.com/industryexpertblogs/24744/motor-control-fpga-vs-dsp.html Hence, by using Alizem Motor Control IP, the motor control designer doesnít have to know about motor control and can spend more time & resources on its true product differentiation while still benefiting of added-value motor control features he/she couldnít have using microcontrollers. Thatís a compelling advantage in many applications. I hope this answers your question.

I'm not convinced that this approach is better than an integrated microcontroller single chip solution with the peripheral set I need and sufficient internal memory to implement the control algorithm. What are the FPGA advantages vs this type of solution?

I'm really starting to get excited about the whole concept of industrial Control (maybe I've been watching to many episodes of "How It's Made" on the Science Channel :-)

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for todayís commercial processor giants such as Intel, ARM and Imagination Technologies.
