Hi, The software that I write needs to comply with the UL1998 Standard. Going through the Standard, I come across many programming techniques that are required yet I don't know anything about. For example, to list just a few, they are Walkpat Memory Test, Cyclic Redundancy Check (CRC)-Single/Double Word, Galpat Memory Test, Time-Slot Monitoring, Dual Channel (Homogeneous) with Comparison... and much more. The Standard has a simple glossary that contains these terms but it gives no ideas as to how practically these are done in the code (especially C code, if that matters). I wonder where I can find references on these techniques. Or where do people learn about them. Is there any books or online resources? Please help. Thank you!
