Now, our challenge is how to describe the to be generator in place to get the balance three implementation.
By looking at the party generated expression, which is the X or of all bits, we'll find out that describing
such an expression requires a parametric, repetitive statement before Rouper statements see as a simple
way to implement such a structures.
Loops in the C C++ functions are controlled by default, well, loops are called the synthesis process
creates a logic for one iteration of the Loop and RTL Design executes this logic.
For each iteration, a loop is executed for the number of iterations as specified by the induction variable.
The number of iterations might also be impacted by the logic inside the loop body, for example, break
conditions or modifications to the loop exit variable.
This Holub statement runs own sequentially, using only one hardware instance of.
This hardware structure requires to transfer data from one generation to the next, which needs a memory,
therefore, the result circuit won't become a national.
As I mentioned before, by default, loops are kept rolled in behind us, therefore the generated hardware
is not a combination of the technique to tackle this issue is to unroll the loop manually or automatically.
This code manually controls the previous loop.
Here we have a statement for each loop iteration done optimized hardware structure is the lander of
X or gaits.
However, most Etchells tools optimized that automatically and generate the binary balance three structure
explained in the previous lecture.
This coat is our previous actualised description for the parity we generate by adding the honorable
pragma to the Falchuk, we rather cellist's unrolled the code automatically.
Fully unrolling the loop creates a copy of Luke Buddy in the article for each loop iteration so that
the entire loop can be run concurrently.
Unrolling allows all iterations to occur in parallel.
Therefore, this code is synthesized into an optimized combination of circuit.
By default, we find ourselves synthesisers a circuit for higher performance, however, adding optimization
can change the sentence as optimization target.
Few of these programs are explained in this course, and most of them that result in sequential circuits
will be explained in a separate course called digital system design, with high level sentences in FPGA
sequential circuits.
Now that we understand the structure of the power to be generator, it is instructive if you develop
our design involved and examine the generated hardware.
This task would be the main concern of the next.
This is our takeaway message and our old for loop representing the parity bit generator can be synthesized
into a combination of.
Now, the police question.
If you assume the bits of data in the generator is 1024, that is W equal 1024, then what is the number
of levels or depth of the final balance?
Three Harmonix or Gaits make the final hardware design.
