This portability is possible because the design can be described with a standard hardware description language (HDL). It must be emphasized that these designs can be easily portable between devices, even from different manufacturers. In general, the trend is to integrate the design in a digital integrated circuit and place around the necessary external components this eliminates the previous inconveniences. In general, the overall design is not flexible and highly dependent on technology and available devices, has long design time, occupies large area, has high power consumption and high delays and low maximum operating frequency. The FPGAs are also available in the market on printed circuit boards, with power and programming connectors, auxiliary memories and input-output pins this avoid to design and construct the printed circuit board, and makes it ideal for prototyping design.Ī transceiver can be designed using discrete electronic components. It must be emphasized that FPGA are integrated circuits reprogrammable by the designer and can be used for different projects, or in a project during its different phases. FPGAs have benefits outweigh the DSP because the FPGA final architecture can be configured in a fully flexible way, in both data and operations size. The FPGA have significant physical benefits, without reaching the performances of ASIC. In the middle are FPGA, which have a reasonable cost for the design of prototypes in general an intermediate cost to the two previous cases. This is because the architecture is rigid, in both data and operations formats. In fact, when the volume of calculus is high, easily they do not have real time response. The DSPs do not have the best physical performances normally they occupy maximum area, have high power consumption and maximum delay.

This technology achieves good physical performances: low area, low power consumption and minimal delays.Īt the other extreme Digital Signal Processor (DSP) can be used which are very cheap ( Maxfield, 2004). In principle, an Application Specific Integrated Circuit (ASIC) can be used ( Maxfield, 2004), but to configure these devices must be sent to the manufacturer, which increases development time and makes more expensive the prototype. Initially, there were several alternatives for the system hardware.
