Oct 22, 2009 ... By Robert Cravotta, Technical Editor DON'T TAKE A CHANCE ON YOUR PROCESSOR SELECTIONS. Welcome to the 36th annual EDN Microprocessor/Microcontroller Directory. There are so many processor options available for embedded-system applications that it is easy to miss the ...
Debugging FPGA designs may be harder than you expect.
Oct 22, 2009 ... By Chris Schalick, GateRocket Bugs can originate at every stage in the FPGA design flow; debugging success depends on using the right tools and methods. In the not-so-distant past, the question used to be, "Can you do that task in an FPGA?" With the advent of modern ...
Astable multivibrator gets hysteresis from positive-feedback stage.
Oct 22, 2009 ... Robert Larson, Seattle, WA Edited by Martin Rowe and Fran Granville Many designs exist for logic-based astable multivibrators, one of the simplest being an RC feedback loop around a single inverting Schmitt trigger inverter (Figure 1 ). The output charges the ...
