The stringent performance constraints and short time to market of modern digital systems require automatic methods for design of high performance applicationspeciﬁc architectures. This paper presents a novel algorithm for automatic generation of custom pipelined data path for a given application from its C code. The data path optimization targets both resource utilization and performance. The input to this architecture generator includes application C code, operation execution frequencies obtained by the proﬁle run and a component library consisting of functional units, busses, multiplexers etc. The output is data path speciﬁed as a net-list of resource instances and their connections. The algorithm starts with an architecture that supports maximum parallelism for implementation of the input C code and iteratively reﬁnes it until an efﬁcient resource utilization is obtained while maintaining the performance constraint. This paper also presents an algorithm to choose the prior...
