[Design Application]
Don't Be Afraid Of Debugging Symmetric Multiprocessing Systems
— Contributing Author

[Design Application]
High Integration Simplifies Signal Processing For CCDs
— Contributing Author

[Ideas For Design]
Microcontroller incorporates eight interrupts
The method presented here provides a microcontroller with eight real-time interrupts instead of just one without giving up any of the processor’s standard I/O lines. This design uses a microcontroller's built-in SCI (Serial Communications Interface)... — Contributing Author

[Ideas For Design]
Overvoltage-tolerant quad buffer used as voltage level shifter
The LCX standard logic product family was designed with overvoltage-tolerant inputs and outputs, enabling users to easily interface LVTTL and 5-V TTL buses. Because the LCX outputs are overvoltage-tolerant when disabled, system designers can take... — Contributing Author

[Ideas For Design]
Build an improved, simpler finite state machine
The two improvements suggested here pertain to the “Build a Simple Finite State Machine” Idea for Design submitted by Giovanni Romeo (ELECTRONIC DESIGN, July 7, 1997, p. 149). First of all, the schematic doesn’t show a register latch on... — Contributing Author

[Ideas For Design]
Simple design equations for thermoelectric coolers
Thermoelectric coolers (TECs) are versatile temperature control devices. They’re best thought of as solid-state heat pumps in which the direction and rate of heat flow can be manipulated by controlling the magnitude and polarity of the TEC drive... — W. Stephen Woodward

[Ideas For Design]
Single-supply random code generator
With the proliferation of satellite receivers, cable systems, and Internet commerce, there’s a real need for secure encryption. A pseudorandom code generator that filled the bill several years ago is now considered “hackable” by many knowledgeable... — Contributing Author

Bob's Mailbox
Readers of this column may remember the letter from Mike McGinn that appeared in the Sept. 15, 1997 Mailbox. Mike had everything he needed to go trekking with Bob—except a working kidney. So,... — Bob Pease
