This system uses the programmable logic device
XC95144XL-TQ100 to implement the interface logic and control logic .
Here, a two-input, two-terminal logic device
, in which output current or resistance between source and drain terminals, is changed by changing the combination of voltages applied to the two-input gates is considered.
Six-hundred, fifty dollars is a little dear for a digital reader (especially when you can buy a full-blown laptop for the same or less), but there have been hints that the Plastic Logic device
will be tremendously cheaper.
The bottom package typically contains a high-density logic device
. Body sizes range from 10 x 10 mm to 15 x 15 mm, with bottom-side ball counts ranging from 240 to more than 400, and package interconnect ball counts ranging from 104 to 160.
The idea was simple--by creating a customizable logic device
based upon SRAM technology, a logic designer could literally develop custom logic devices
directly on his desktop, doing away with the high upfront costs and long development cycles typically associated with ASICs.
Market share also soared: In 2002, Xilinx boasted nearly 50 percent of the programmable logic device
market share, up from 50 percent four years earlier.
Netherlands contractor Philips Semiconductors is claiming that the company's new 3 V PZ3032 complex programmable logic device
's (CPLD) 8 ns delay from any input to any output is 25 percent faster than its nearest competitor device.
The company said its Lattice MachXO2 programmable logic device
(PLD) is used to interface the image sensor bridge design with the Sony IMX136 image sensor, which is suitable for surveillance and industrial cameras.
In addition, almost all complex programmable logic device
(CPLD) and FPGA manufacturers, such as Altera, Lattice and Xilinx, have incorporated boundary scan logic into their components, including additional circuitry that uses the boundary scan four-wire JTAG interface to program their devices in-system.
But the Plastic Logic device
has a screen that is two and a half times the size of Kindle so it is better sized, the company argues, for newspaper use.
This allows any logic device
, PLC, or remote I/0 node to activate or deactivate the power supply output power for easy system startup/shutdown or maintenance purposes.
"Because two ports can handle the data flow from the physical layer device to the rest of the system, the remaining two free ports can be connected to a processor or programmable logic device
to control and manipulate the data.
