the Virtex-4 FX family's embedded PPC405. LSI SAS LSI uses the PowerPC 440 core in a number of its SAS controller chips, including the widely used SAS2008 variant. Acalis CPU872 The Acalis CPU872 is a highly specialized Security SoC chip built by CPU Tech. It is designed for highly sensitive and mission critical systems such as military applications. It has provisions to prevent tampering and reverse engineering and is manufactured at IBM's highly secure Trusted Foundry. It has embedded DRAM, dual 440 cores with dual precision FPUs and auxiliary computing units providing acceleration and protection for communications, complex algorithms and synchronization between cores. PowerPC 450 The processing core of the Blue Gene/P supercomputer is designed and manufactured by IBM. It is very similar to the PowerPC 440 but few details are disclosed. Blue Gene/P The Blue Gene/P processor consists of four PowerPC 450 cores running at 850 MHz reaching 13.6 gigaflops in total. IBM is claiming very power efficient design compared to other supercomputer processors. PowerPC 460 Introduced in 2006, the 460 cores are similar to the 440 but reach 1.4 GHz, are developed with multi-core applications in mind and have 24 additional digital signal processing (DSP) instructions. The cores are designed to be low-power but high performance and the 464-H90 is expected to draw only 0.53 W at 1 GHz. The 460 core adheres to Power ISA v.2.03 using the Book III-E specification. PowerPC 460S a completely synthesized core and can be licensed from IBM or Synopsys for manufacturing on different foundries. 460S can be configured with different amounts of L1 and L2 cache as well as with or without SMP and FPU. PowerPC 464-H90 a 90 nm, hard core (not synthesizable), released in 2006, will offer a customizable core for ASICs that can be manufactured with IBM or at manufacturing facilities at Chartered or Samsung. PowerPC 464FP-H90 released in 2007, is a hard core that adds a double precision floating point unit (FPU). AppliedMicro PowerPC 460SX and 460GTx are based on the 464-H90 core. They are targeted towards very high-end storage and networking applications, respectively. They run at 0.8 to 1.2 GHz, have 512 KB of L2 cache that doubles as SRAM storage, a 400 MHz clock DDR2 memory controller, four Gigabit Ethernet controllers, PCIe controllers and a variety of application-specific accelerators and controller facilities. They are manufactured on a 90 nm process. APM82181 a 0.8–1 GHz 464-based
