    摘要: Division operation is very important in the computer system. Nowadays people use a hardware module─divider to implement the division algorithm. Conventionally synchronous techniques are applied to implement the divider. The synchronous systems always need system clock signals to trigger the system. However, the system clock of the synchronous system may cause some problems, such as clock skew, dynamic power consumption, ..., etc. Compared to synchronous systems, asynchronous circuits do not need system clock signals and thus the asynchronous system does not have the shortcomings mentioned above. Here we will propose a new asynchronous architecture for the divider. In this asynchronous scheme, the architecture is of simplicity and is very easy for the VLSI implementation. By this asynchronous architecture, we use TSMC’s 0.6um SPDM process to design a 32-b/32-b radix-2 non-restoring divider and the spice simulation proves it works. The HSPICE simulation shows that it can finish a 32-b/32-b division in between 3.7ns to 160.2ns.
