POWER PC (POWER4,5,6) POWER The term stands for Performance Optimized With Enhanced RISC, which IBM has designed a system POWER in such a way that the architecture of large and complex, but it also can not be called POWER microprocessor, one that will bring the POWER source. the chip is then applied It requires a lot of chips until the IBM has partnered with the company to develop MOTOROLA POWER PowerPC, which is enough to be called. A one-chip microprocessor architecture POWER PC software supports multiple formats that target the PowerPC architecture still maintains applications in a variety of formats, such as. Application on Macintosh Application of A / X or UNIX other reasons of cooperation. The chip between Motorola and IBM itself makes Motorola. Reduction activities focused on RISC chips, which is 88 110 of its own, but Motorola also continues to build on. The proposed agreements with auto manufacturers in the US to use its RISC chip to develop control systems in cars. But also continue to cooperate with IBM to develop the PowerPC chip architecture used by some of the tribe of 88,110 and highlight the links of the two technologies together IBM's POWER architecture design. POWER architecture in a manner that is large and complex. It is sometimes difficult to say that a microprocessor. If the application is the chip will require a lot of chips. When partnered with Motorola and POWER PC is used only a single chip, thus it is called. A microprocessor can honestly POWER architecture has been developed and brought to market since last year.. 2533 has improved previous SPARC chip MIPS4000 or up to two years old infrastructure of architecture. POWER used to generate a RS / 6000 requires multiple chips. The structure consists of a small chip. And served in the early chip includes a RS / 6000 to 7 contains 8 FXU: Fixed Point Unit 8 FPU: Floating Point Unit 8 ICU: Instruction Cache Unit POWER architecture is combined. RS / 6000 in units of chips, DCU is the fourth time and will include a complete system will require additional chips to the SCU: Storage Control Unit and IOU: I / O Unit, which serves to connect the components together outside. Due to the complexity of the POWER architecture, it requires a very high number of transistors. A separate chip sub 7 chips, each chip technology 1 micron transistors about one million displays details of each chip, which assembled the RS / 6000, which requires a piece of silicon combination of size 2 inches square. a total of 6.9 billion transistors and built a transistor that uses a lot of CPU and. More than any other microprocessor chips In the same period (80 486 one-transistor 1.2 million, as well as the number of chips in a single chip DCU) chip assemblies. RS / 6000 , the structure of links, each chip is 32 bits using DCU all four chip enables caching for data 64 times by linking the login information for simultaneous processing of up to 128 bytes and units. memory on a memory is ECC can detect errors and correct them and for ICU memory cache for the eight times the connection bus between the chip connecting bus between chips inside the CPUs. the structure of the RS / 6000 has a working unit calculates both integer and real number at the same time we call the ALU rather than one that is super-scalar execution units in the statement cache. (ICU) to pull orders separately submitted to both the FPU and FXU simultaneously, making each cycle run more than one command, each command that runs FPU and FXU will receive the DCU to process the information. this information comes from the DCU processing real number up to 64 bits, thereby making processing numerical work better.
