Parallel vs Serial Data Transmission

Parallel and serial data transmission are most widely used data transfer techniques. Parallel transfer have been the preferred way for transfer data. But with serial data transmission we can achieve high speed and with some other advantages.

In parallel transmission n bits are transfered simultaneously, hence we have to process each bit separately and line up them in an order at the receiver. Hence we have to convert parallel to serial form. This is known as overhead in parallel transmission.

Signal skewing is the another problem with parallel data transmission. In the parallel communication, n bits leave at a time, but may not be received at the receiver at the same time, some may reach late than others. To overcome this problem, receiving end has to synchronize with the transmitter and must wait until all the bits are received. The greater the skew the greater the delay, if delay is increased that effects the speed.

Another problem associated with parallel transmission is crosstalk. When n wires lie parallel to each, the signal in some particular wire may get attenuated or disturbed due the induction, cross coupling etc. As a result error grows significantly, hence extra processing is necessary at the receiver.

Serial communication is full duplex where as parallel communication is half duplex. Which means that, in serial communication we can transmit and receive signal simultaneously, where as in parallel communication we can either transmit or receive the signal. Hence serial data transfer is superior to parallel data transfer.

Practically in computers we can achieve 150MBPS data transfer using serial transmission where as with parallel we can go up to 133MBPS only.

The advantage we get using parallel data transfer is reliability. Serial data transfer is less reliable than parallel data transfer.

Setup and Hold TIme

Every flip-flop has restrictive time regions around the active clock edge in which input should not change. We call them restrictive because any change in the input in this regions the output may be the expected one (*see below). It may be derived from either the old input, the new input, or even in between the two. Here we define, two very important terms in the digital clocking. Setup and Hold time. The setup time is the interval before the clock where the data must be held stable. The hold time is the interval after the clock where the data must be held stable. Hold time can be negative, which means the data can change slightly before the clock edge and still be properly captured. Most of the current day flip-flops has zero or negative hold time. In the above figure, the shaded region is the restricted region. The shaded region is divided into two parts by the dashed line. The left hand side part of shaded region is the setup time period and the right hand side part is the h

Digital Design Interview Questions - All in 1

1. How do you convert a XOR gate into a buffer and a inverter (Use only one XOR gate for each)? Answer 2. Implement an 2-input AND gate using a 2x1 mux. Answer 3. What is a multiplexer? Answer A multiplexer is a combinational circuit which selects one of many input signals and directs to the only output. 4. What is a ring counter? Answer A ring counter is a type of counter composed of a circular shift register. The output of the last shift register is fed to the input of the first register. For example, in a 4-register counter, with initial register values of 1100, the repeating pattern is: 1100, 0110, 0011, 1001, 1100, so on. 5. Compare and Contrast Synchronous and Asynchronous reset. Answer Synchronous reset logic will synthesize to smaller flip-flops, particularly if the reset is gated with the logic generating the d-input. But in such a case, the combinational logic gate count grows, so the overall gate count savings may not be that significant. The clock works as

Synchronous Reset vs. Asynchronous Reset

Why Reset? A Reset is required to initialize a hardware design for system operation and to force an ASIC into a known state for simulation. A reset simply changes the state of the device/design/ASIC to a user/designer defined state. There are two types of reset, what are they? As you can guess them, they are Synchronous reset and Asynchronous reset. Synchronous Reset A synchronous reset signal will only affect or reset the state of the flip-flop on the active edge of the clock. The reset signal is applied as is any other input to the state machine. Advantages: The advantage to this type of topology is that the reset presented to all functional flip-flops is fully synchronous to the clock and will always meet the reset recovery time. Synchronous reset logic will synthesize to smaller flip-flops, particularly if the reset is gated with the logic generating the d-input. But in such a case, the combinational logic gate count grows, so the overall gate count savings may not be
