Recurrence relation

A recurrence relation or recursive relation is an equation that represents a function in terms of the values of its smaller inputs. Every recurrence relation T(n) is a recursive function of integer n and consists of a base case and a recursive case.

Question

4- Assume that we have 16 LEDS connected to our discovery board
at PORTD from pin0 to pin 15 and assume that PORTD is initialized
to work as a push pull output and the clock has been enabled for
PORTD and the mode of the PINS connected to led has been
chosen to be in output mode and the register GPIOD_ODR is used
to write the output to the pins so that when the output is 0 the
LED is off and vice-versa. Answer the following question
int i;
for (i=0;i<16;i++){
GPIOD_ODR |=(1<<i);
if(i>=2){
GPIOD_ODR &="(1<<(i-2));
}
}
At each iteration what is LEDS that will be on from LEDO
connected to PDO to LED15 connected to PD15.

Part III Design and implement a circuit that successively flashes digits 0 through 9 on the 7-segment display HEXO. Each digit should be displayed for about one second. Use a counter to determine the one-second intervals. The counter should be incremented by the 50-MHz clock signal provided on the DE-series boards. Do not derive any other clock signals in your design-make sure that all flip-flops in your circuit are clocked directly by the 50-MHz clock signal. A partial design of the required circuit is shown in Figure 2. The figure shows how a large bit-width counter can be used to produce an enable signal for a smaller counter. The rate at which the smaller counter increments can be controlled by choosing an appropriate number of bits in the larger counter. Counter 50 MHz Clock Counter ...

In verilog a counter must be developed from 0 to 9999 with a reset and parallel loading. The reset will be a button in charge of returning the count to 0 when pressed.For this practice, the implemented circuit will only use a 7-segment BCD converter module, which will have to be managed between the different 7-segment displays at a given frequency.

A Moore sequential circuit has three inputs (X2, X₁, and Xo) that specify a temperature range in a room. The circuit has two outputs (I and D) that control a heater for the room; I = 1 causes the heater to increase its heat output, and D = 1 causes the heater to decrease its heat output. If the temperature range is 0, 1, or 2 for three successive clock cycles, the circuit generates I = 1, and conversely if the temperature range is 5, 6, or 7 for three successive clock cycles, the circuit generates D = 1; otherwise, I = 0 and D = 0. 1.
