Hello Everybody....Need urgent help....I am trying to understand the above topic for my test on Tuesday Next Week....
Would Anybody please explain to me how I would do the below using ASM method:
"A circuit is required to control an ADC (Analogue to Digital Converter) by
asserting a control signal called SC ("Start Conversion") and waiting for a
status signal called EOC ("End Of Conversion") to go high. You may deassert
SC when you receive a high on the EOC status signal whereupon
EOC will drop low within a microsecond. The circuit should take eight
readings at 1 second intervals and output an average value to a DAC
(Digital to Analogue Convertor). The DAC requires a STROBE control to
be asserted after the data; you should keep STROBE asserted until the
DAC asserts its ACK status signal to confirm it has accepted the data.
You can then drop the STROBE signal and the ACK status line will drop
low within a microsecond. Assume a system clock of 1MHz is available
and also a module called DIV-1M that divides the system clock rate by
one million."
Even A rough Block diagram would be helpful...
Thanks
