Embodiment Construction

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0042] Such as figure 1 and figure 2 As shown, when the existing parallel-to-serial conversion circuit performs parallel-to-serial conversion (taking eight to one as an example), a multi-level tree-shaped parallel-to-serial conversion circuit composed of multiple MUXs is established according to requirements, and each conversion path in the circ...

Abstract

The invention provides a parallel-to-serial conversion circuit, comprising: an inverter and N dynamic flip-flops; N is the same as the number of bits of parallel data received; the output ends of the N dynamic flip-flops are all connected to the input ends of the inverter Connection; the data receiving end of the nth dynamic flip-flop receives the nth data in the N-bit parallel data, and the clock signal receiving end of the nth dynamic flip-flop receives the nth clock signal; wherein, the clock period of each clock signal They are all the same as the update cycle of N-bit parallel data, and the high levels of each clock signal do not overlap, the circuit structure of each dynamic flip-flop does not include an inverter, and the value of n is a positive integer from 1 to N. The parallel-serial conversion circuit provided by the invention simplifies the structure of the parallel-serial conversion circuit, reduces the timing requirement on the path and reduces the occupied area of ​​the circuit.

Description

technical field [0001] The invention relates to the field of computers, in particular to a parallel-to-serial conversion circuit. Background technique [0002] In the field of integrated circuits, when the processor in the chip processes data, it usually uses multi-digit binary numbers to process data in parallel to improve the computing power. However, when the chip outputs data externally, each pin of the chip can only output one pin. bit data. More pins will result in a larger chip area, and the chip area is proportional to the cost of making the chip. Therefore, in order to save money, the output parallel data needs to go through a parallel-to-serial conversion circuit before reaching the pins of the chip. Line data, and then output the serial data through a pin, thereby reducing the number of pins required. [0003] figure 1 It is a schematic diagram of an existing 8-to-1 parallel-to-serial conversion circuit, figure 2 for figure 1 Schematic diagram of the circuit...
