buffer - Canonical term for "simultaneous data-latching" -


i have module (in case on fpga) several input values (registers) updated sequentially (if @ all), copied in parallel in single, atomic step guarantee coherency during following data processing steps. there common term this?

  • "double-buffering" comes close, refers 2 buffers in parallel swapped, while i'm copying them "forward".
  • "simultaneous data-latching" i'm using @ moment, sounds unfamiliar...

here store_1, store_2 , store_all write-enable signals registers, synchronously clocked same clock.

looks basic shift-registers me.

this type of arrangement might called retiming registers if there presence purely ease routing pressure 'module'. or perhaps pipelining registers if inserted maintain specific alignment between 'value_1/value_2' , 'outputs', if latency through module changed @ point.

if control signals store_1 / store_2 /store_all infact clocks, may called synchronisation stages, although design has problems in case.

your question mixes words tangentially related digital logic timing, without being specific.

Android soft keyboard reverts to default keyboard on orientation change -

i'm building android soft keyboard , can't seem fix bug - have arabic , qwerty keyboard , when rotate device on qwerty keyboard (or arabic shift), it's if program has "restarted" , becomes arabic keyboard without shift. the onsaveinstancestate(bundle savedinstancestate) not work because application not extend activity inputmethodservice . i put following in android manifest android:configchanges="keyboard|keyboardhidden|orientation" android:windowsoftinputmode="stateunchanged|adjustresize"> i tried using @override public void onconfigurationchanged(configuration newconfig) { super.onconfigurationchanged(newconfig); log.i(mydebug, "config changed " + currentkeyboard.equals(qwerty)); } however, currentkeyboard.equals(qwerty)) results false , made sure true before orientation change. any appreciated. i think applications fault. if application restarting on orientation change

Rendering JButton to get the JCheckBox behavior in a JTable by using images does not update my table -

i rendering jbutton image on simulate jcheckbox behavior. why don't let jtable render jcheckbox? because need bigger checkboxes , there's no way can resize them (as far know). so, have own table cell renderer , editor. both renders jbutton , checkbox images on them. trying change image checked image unchecked image (or vice versa) , update cell value (boolean true or false). however, reason, getcelleditorvalue() not update table. so, release mouse, value goes original one. any appreciated! lot! public class tableexample extends jframe { jscrollpane pane; jpanel panel; jtable table; object[][] data; mytablemodel tm; renderer buttoncolumn; public tableexample(object[][] data) throws ioexception { string[] columns = {"column#1", "column#2", "column#3", "column#4", "column#5", "column#6"}; this.data = data; this.setpreferredsize(new dimension(700, 500));
