Dual-Core Processors Satisfy Extended Reliability Requirements
Two dual-core integrated processors from e2v, the PC8641D and the PC8572, are extended-reliability versions of the MPC8641D and MPC8572 from Freescale Semiconductor. The MPC8641D features two superscalar e600 cores running at up to 1250 MHz in a military temperature range of -55°C to +125°C. The e600 core has a 128-bit vector processing unit. With 1 MB of backside L2 cache for each core, combined with a dual 64 bit DDR2 memory controllers, the 8641D features system interconnect and communication interfaces including a 4-lane Serial RapidIO port, two 8-lane PCI-Express ports, and four Gigabit-Ethernet controllers. The PC8572 integrates two e500 processor cores, which can operate at up to 1200 MHz with an extended temperature range of -40°C to +110°C. The PC8572 also features 1 MB of on-chip L2-cache, and a dual DDR2/DDR3 memory controller.
