Design and Implementation of the Asynchronous Sub-Word Parallel MAC Unit
Zhiying Wang · Computer Engineering and Science · 2009
The problems such as clock skew and high power consumption may exist in synchronous integrated circuit design,which can be well solved in asynchronous design.A 32-bit asynchronous sub-word parallel MAC unit in adopting the asynchronous integrated circuit design method is presented in this paper.And it is implemented in the 0.18μm process.The MAC unit we design supports various sub-word parallel models using a special partial product decode circuit.It is suitable for multimedia processing.The test results indicate the performance and power consumption of this asynchronous MAC unit are superior to the synchronous counterpart.
