Processor replication with IP rights eliminates errata

Rochester Electronics offers replication of processors through its Semiconductor Replication Process (SRP). There are several companies within the semiconductor industry selling their emulated versions of popular processors originally produced by Freescale and Intel. Because Rochester receives processor IP from the original manufacturer, there is no need to emulate.

Rochester’s methodology is essentially a fab porting exercise, similar to methods that other companies use when transferring a product from one fabrication facility to another. The end product is the same die size, same transistor count, same interconnect, and within specs the original manufacturer would have shipped, with no software errata.

Emulated processors feature errata, compared to the original product, whereas replicated processors from Rochester do not.

"Emulated processors are produced in a different technology node from the original, which potentially introduces unexpected behaviour after a customer has fully populated their boards and extensively tested at the system level with real code,"  commented Dan Deisz, Director of Design & Technology, Rochester Electronics. "Replicated processors from Rochester do not have this problem. Our customers receive a true replacement with no surprise errata on processors."
