32-bit and 64-bit PowerPC processors have been a favorite of embedded computer designers. To keep costs low on high-volume competitive products, the CPU core is usually bundled into a system-on-chip (SOC) integrated circuit.
Yellow Dog Linux, full support for 32/64-bit; PS3; Void Linux, support in third-party fork [27] for 32-bit and 64-bit (big-endian and little-endian) Solaris 2.5.1 PowerPC edition on the PReP platform OpenSolaris, experimental [28] [29] JavaOS; Windows NT 3.5, [30] 3.51 and 4.0; ReactOS, PowerPC port no longer under active development [31]
The PowerPC 970 was released in 2003 and was one of the first 64-bit processors developed for consumer-type computers, PowerMac G5 in this case.. ppc64 is an identifier commonly used within the GNU/Linux, GNU Compiler Collection (GCC) and LLVM free software communities to refer to the target architecture for applications optimized for 64-bit big-endian PowerPC and Power ISA processors.
Addition of 1 GiB and 4 GiB variable-page sizes; Addition of DPESFP (double-precision embedded scalar floating point) support. Building on top of SPESFP, these instructions access both halves of the 64-bit integer register. Doubling in size and associativity of the MMU's second-level 4K-page array (from 256-entry 2-way to 512-entry 4-way)
The core implements most [1] of the core of the Power ISA v.2.06 with hypervisor support, but not AltiVec. It has a four issue, seven-stage out-of-order pipeline with a double precision FPU , three Integer units , 32/32 KB data and instruction L1 caches , 512 KB private L2 cache per core and up to 2 MB shared L3 cache.
AltiVec prior to Power ISA 2.06 with VMX lacks 64-bit integer support. Developers who wish to operate on 64-bit data will develop routines from 32-bit components. For example, below are examples of 64-bit add and subtract in C using a vector with four 32-bit words on a big-endian machine. The permutes move the carry and borrow bits from columns ...
The Java language has undergone several changes since JDK 1.0 as well as numerous additions of classes and packages to the standard library.Since J2SE 1.4, the evolution of the Java language has been governed by the Java Community Process (JCP), which uses Java Specification Requests (JSRs) to propose and specify additions and changes to the Java platform.
A Pocket PC (P/PC, PPC) is a class of personal digital assistant (PDA) that runs the Windows Mobile operating system, which is based on Windows CE/Windows Embedded Compact, and that has some of the abilities of modern desktop PCs. The name was introduced by Microsoft in 2000 as a rebranding of the Palm-size PC category and was marketed until 2007.
