Quick Draw - The object of Quick Draw is to test your reaction
time against your opponent's. A third person acts as a referee and begins
the duel by pressing S1, which lights LED1. Upon seeing LED1 go on, you
try to outdraw your opponent by ….(added 05/08) |

Scheme adds sequencing and shutdown control to regulator -
30-Oct-03 Issue of EDN Modern microprocessor- or FP-GA-based
circuits require separate and independent power-supply voltages for the
core and the I/O circuits..... [Design Idea by Said Jackson, Equator
Technologies Inc, Campbell, CA] |

Simple circuit provides power sequencing - 14-Oct-04 Issue of EDN
ASICs, FPGAs, and DSPs can require multiple supply voltages with restrictions on their
start-up sequencing. Often, I/O voltages, which usually have the highest voltage, must
come up first, followed by all other voltage rails in a high-to-low order, with the
core voltage last. This scenario may also require that one supply rail not
exceed another bythan a diode drop; otherwise, excessive c..... [Design Idea by John
Betten, Texas Instruments, Dallas, TX] |

Simple FIFO provides data width conversion - 26-Sep-02 Issue of EDN
Many designs require FIFO elastic buffers to form a bridge between subsystems with
different clock rates and access requirements. However, in some applications, you need
FIFO buffers for data conversion. One example is the case in which you need to connect
an 8-bit ADC to a 16-bit data-bus microprocessor through a FIFO buffer (Figure 1].....

Stereo Loopback Circuit - that accepts a digitized stereo signal from the
ADC of the XStend Board codec and loops the signal back to the codec DAC stage for
output as a stereo signal. (added 4/02) |

Swapping bits improves performance of FPGA PWM counter - 13-Sep-07 Issue of
EDN A simple change to the specification of an FPGA counter lowers the ripple of
a PWM counter functioning as a DAC..... [Design Idea by Stefaan Vanheesbeke, Ledegem,
Belgium] |

Tool generates HDLs directly from Simulink - 09/19/06 EDN-Design
Ideas.....The folks trying to model multiple DSP functions to implement in FPGAs or
ASICs using MathWorks tools will be happy to learn that the company's latest release,
Simulink HDL Coder, automatically generates cycle-accurate, bit-accurate Verilog or
VHDL directly from Simulink..... [Design Idea by Michael Santarini, Senior Editor --
EDN] |

USB Macro - that combines a complete USB transaction layer with an 8051
microcontroller core and a functional block that implements the application-specific
functions. This macro was developed and is supported by Trenz Electronics for
use with an XSV Board. (added 4/02) |
