As a rule, dynamic hazards are more complex to resolve, but note that if all static hazards have been eliminated from a circuit, then dynamic hazards cannot occur. Functional hazards. In contrast to static and dynamic hazards, functional hazards are ones caused by a change applied to more than one input.

WebJan 28, 2014 · In the end, what I intend to have is a processor that draws in the framebuffer stored in SDRAM. Then, a page flip occurs and VGA starts to fetch the new picture that was drawn by the processor. To instruct the VGA to fetch from the new location, I would like to inform the VGA controller (using memory mapped io) the new address of the new image. WebJan 15, 2013 · If n is static per simulation run, then use a generic. If n needs to change during the simulation, then either dynamically create the std_logic_vector, or use a vector with a width that is the maximum value for n. In that case, use a subtype for port n that restricts the values for n, eg., subtype n_t is natural range 0 to 2000.
