FIFO(first in first out) in VHDL

The FULL flag will be a warning: When the memory is full, the Full flag will come with logic 1 and indicate that the memory is completely full. It will not accept the PUSH command. -EMPTY will be a flag warning: When the memory is completely empty, the Empty flag will come logic 1 and inform the output that the memory is completely empty. It will not accept the POP command. - Among PUSH, POP and SWP commands, POP will have 1st priority and PUSH will have 2nd priority. In other words, if more than one command comes, POP will be processed first and then PUSH will be processed. The -RST command will take precedence over all commands. -NOPOP will be a flag warning. If the POP command cannot be executed due to a dangerous reason, NOPOP will be output and a warning signal will be transmitted to the output. -NOPUSH flag stimulus. If the PUSH command cannot be executed for some reason, the NOPUSH flag warning will be output and the warning signal will be transmitted to the output. - SWP MUST HAVE COMMAND please help me
