Special Topics of Data Path Synthesis,ocess great volumes of data. Self-timing is the topic of the second section. To some extent it can be considered as an extension of the pipelining concept and is especially attractive in the case of very big circuits.

上下倒置

Control Unit Synthesis, and synthesize the control unit from a functional description of the complete circuit (Chap. 5). Nevertheless, in some cases the digital circuit designer can himself be interested in performing part of the control unit synthesis.

Adders,ized adders. As a consequence, in many cases the synthesis tools are able to generate fast and cost-effective adders from simple VHDL expressions. Only in the case of relatively long operands can it be worthwhile to consider more complex structures such as carry-skip, carry-select and logarithmic ad

Dividers,n and multiplication, division is generally not included as a predefined block within FPGA families. So, in many cases, the circuit designer will have to generate dividers by choosing some division algorithm and implementing it with adders and multipliers.

無能力

Other Operations,onversely, is dealt with in Sects. 10.1 and 10.2. An important particular case is . = 10 as human interfaces generally use decimal representations while internal computations are performed with binary circuits.

確定無疑

Floating Point Arithmetic,sion. In such cases, instead of encoding the information in the form of integers or fixed-point numbers, an alternative solution is a floating-point representation. In the first section of this chapter, the IEEE standard for floating point is described. The next section is devoted to the algorithms
