the topic is about wrting vhdl code, Please provide general information about the attached diagram that I can include in my report just information no need for code, given requirment is $"$If reset is $1,$

the count value becomes $00.$

Otherwise:

If enable is $1,$

When the rising edge of the clk signal occurs,

If up$\_$down is $1,$the count value increments,

If up$\_$down is $0,$the count value decrements.

Note:

$*)$The counted value can be held as an intermediate value. After defining it$,$the initial value can be assigned as follows:

signal count: std$\_$logic$\_$vector$(7$downto $0)$:$="00000000"$;

$*)$For the rising edge of the clk signal, you can use if$($rising$\_$edge$($clk$)).$

$*)$To convert std$\_$logic$\_$vector to integer, use the conv$\_$integer$(...)$function$.$

$*)$To convert an integer to std$\_$logic$\_$vector, use the conv$\_$std$\_$logic$\_$vector$(...,4)$function$.$

$*)$To find the tens place of the counted value, divide by $10$:

bcdconv$\_$std$\_$logic$\_$vector$(($conv$\_$integer$($input$\_$value$)/10),4)$;

$*)$To find the units place of the counted value, take the modulus $10$in base $10$:

bcdconv$\_$std$\_$logic$\_$vector$(($conv$\_$integer$($input$\_$value$)$mod $10),4)$;$"$
