Freescale Semiconductor Inc., the chip company formed out of the Semiconductor Products Sector of Motorola Inc., has disclosed the existence of a dual processing core PowerPC processor, the MPC8641D, described as the company's "most powerful processor to date".

The company made the announcement at the Smart Networks Developer Forum. It did not disclose whether the processor has been realized in silicon, or when it would become available to customers.

The processor is designed for implementation using a 90nm silicon-on-insulator manufacturing process and is intended for use in networking, telecom, military, storage and pervasive computing applications, Freescale said. The MPC8641D device integrates two e600 PowerPC cores with each processor able to operate at a clock frequency of 1.5GHz. There are two 1MB L2 caches and dual AltiVec vector processing engines. The dual processor is expected to consume between 15W and 25W in typical use. "In designing the MPC8641D processor, Freescale has made significant strides in eliminating traditional system-level bottlenecks that can restrict processing bandwidth," said Linley Gwennap, president and principal analyst of The Linley Group, in a statement issued by Freescale. "Not only can the processor's integrated MPX bus deliver more than three times the performance of an external bus, but the integrated high-speed interconnects can help ensure that the cores will be efficiently utilized. System developers should be pleased with the performance gains," he also said.

Although Freescale unveiled the MPC8641D to the general public and press on Tuesday (Sept. 28), it said it had discussed the processor with third-party suppliers and said that Enea Embedded Technology, Green Hills Software, Metrowerks, QNX and Wind River have committed their support for the architecture.
