E-book opens way to FPGA in-line, in-system programming
Programming memory on the manufacturing line after the devices have been soldered to a circuit board must be accomplished quickly to keep pace with the assembly process. Unfortunately, the capacity of flash has got so large and the amount of data being programmed into them so extensive that the process has slowed considerably.
A new eBook published by ASSET InterTech explains how distributed architectures and on-board field programmable gate arrays (FPGA) accessed via JTAG can be deployed to accelerate in-line in-system programming (ISP) without jeopardising the manufacturing beat rate.
“Parallel programming – or loading data into multiple circuit boards simultaneously – speeds up the process by orders of magnitude,” said Kent Zetterberg, technical product manager for the ScanWorks platform for embedded instruments. “In addition, a programming engine can be temporarily inserted into an on-board FPGA to program multiple devices on the same board at the same time. When you start adding up all of the factors, you’ve got a really fast in-line programming process.
” Titled “Fast Flash Parallel In-System Programming”, the new eBook is available for free and can be downloaded from the eResources center on the ASSET website.
