Replicated processors: reliable alternative to emulation for legacy substitutions

November 20, 2014 // By Graham Prophet
Rochester Electronics’ business is in mature and end-of-life semiconductors: supplying parts, or acceptable replacements, for devices no longer available from their original manufacturers. The company offers replication of processors, a preferable alternative to a less reliable device emulation, through its Semiconductor Replication Process (SRP).

Emulated versions of popular processors originally produced by Freescale and Intel are available from several sources, Rochester notes. The company offers devices based on processor intellectual property (IP) it receives from the original manufacturer; there is no need to emulate. Rochester's methodology is essentially a fab porting exercise similar to what those companies would do 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 have new errata as compared to the original product. Replicated processors from Rochester Electronics, says the company, do not.

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

Authorised by more than 60 leading semiconductor manufacturers, Rochester acquires all remaining finished devices, wafer/die, and available intellectual property in order to manufacture the exact same device and provide a reliable, continuing source of semiconductors used in critical systems worldwide - in any quantity and for as long as needed.
