In digital hardware the elemental memory element may
be a flip-flop or other such device which represents a ___
(bit, byte). In analog hardware, the device might be a CCD
(charged coupled device) as in a digital camera. Each CCD
represents a ___ (bit, byte) when converted to digital data.
In software, a register will commonly hold a word which
is a ___ (bit, byte) wide. (use http://www.onelook.com
Look up and download data sheets for
the 74LS194 and 74HC164 shift register ICs. (use www.fairchildsemi.com)
Look up Intel microprocessors and report on the register
size on many of their processors. Some of the processors
include the Celeron, Pentium II, Pentium III, Pentium 4,
Athlon, and Duron.
Refer to the figure below and describe the characteristics
of each of the four byte-wide registers. <a onClick="window.open('/olcweb/cgi/pluginpop.cgi?it=gif::::/sites/dl/free/0073126349/443700/fig9_1.gif','popWin', 'width=NaN,height=NaN,resizable,scrollbars');" href="#"><img valign="absmiddle" height="16" width="16" border="0" src="/olcweb/styles/shared/linkicons/image.gif"> (11.0K)</a>
Using circuit simulation software, construct and operate
an 8-bit shift register using the 74HC164 IC. Test the circuit
and show the results to your instructor.
