PPCM2 6U VME dual PowerPC Processor

The PPCM2 further extends Radstone's XtraPower family of dual processor boards, offering high-performance processing and I/O interfaces from two fully independent compute nodes. With enhanced high bandwidth inter-board communications via 2eSST VME and onboard StarFabric, PPCM2 is ideal for a wide range of compute-intensive, real-time applications.

Each compute node features the latest PowerPC® 7448 processor and Discovery III Integrated System Controller supporting high capacity DDR SDRAM, Flash memory and NVRAM. In addition each node supports its own dedicated I/O resources including GPIO, Serial and Gigabit Ethernet plus its own PCI-X-capable PMC. Shared resources include further GPIO and USB 2.0 plus 2eSST VME and two StarFabric ports.

The PPCM2's loosely coupled architecture targets demanding real-time applications with each node running separate instances of the chosen operating system. Mission-critical applications can also benefit from Radstone's comprehensive Deployed Test software for the PPCM2.

IBM Unveils Dual-Core PowerPC 970MP Chip

Category: CPU

IBM on Friday introduced its latest addition to the PowerPC processor lineup that will soon be used in Apple’s Power Mac computers. Apart from the second core, from functionality standpoint, the chip, which was code-named Antares, seems to be similar to currently available PowerPC 970FX central processing units.

At Power Everywhere forum in Tokyo, Japan, IBM released some details about the PowerPC 970MP processor it had been working with for more than a year. Unfortunately, not a lot of information has been let out.

IBM’s PowerPC 970MP processor has two PowerPC 970FX-like 32-/64-bit processing engines inside, each of the cores have dedicated 1MB level-two cache. While initially some sources suggested that IBM’s dual-core chip for desktops, workstations and blade servers would be clocked at up to 3.0GHz, commercial chips will operate in the range of 1.40GHz – 2.50GHz, a bit lower compared to the speed of the current top-of-the-range PowerPC 970FX product that works at 2.70GHz.

The PowerPC 970MP is expected to feature a copper bus with 10 layers of metal: the dual cores will share a single Elastic Interface (EI) bus supporting a wide range of bus ratios and opening the door for higher than 1000MHz bus speeds, according to previous reports. The new microprocessor supports symmetric multiprocessing SMP, which allows to install two or more such chips in a system.

IBM’s latest central processing unit (CPU) features power saving technology called PowerTune. The frequency and voltage of both cores can be scaled downward to reduce the power during periods of reduced workload. For further power savings, each core can be independently placed in a power-saving state called “doze”, while the other core continues operation. Moreover, one of the cores can be completely de-powered during periods of less stringent performance requirements.

While IBM does not provide any details about power consumption of the chip, it is unlikely that it is too high, as the firm positions the PowerPC 970MP not only for desktops, workstations and blade servers, but also for embedded applications that typically require low power consumption of its components.

IBM did not specify whether the new CPU sports any advantages, such as virtualization, over the predecessor in addition to the second core. It is likely that the PowerPC 970MP inherited the complete functional heritage of the PowerPC 970FX.

IBM’s PowerPC 970MP chip is made using 90nm CMOS SOI10K fabrication process at IBM. The die size was reported to be 154 square millimeters, about 25% lower than that of Intel Pentium D microprocessor. The new PowerPC 970MP chips feature ABIST (array built-in self-test) diagnostic for test and qualification simplifications.

It is unclear when IBM starts commercial shipments of the PowerPC 970MP.

Intel® PXA27x processor family

Designed from the ground-up for wireless clients and incorporating the latest Intel mobile technologies, the Intel® PXA27x processor family redefines what a wireless handheld can do. Intel PXA27x processors are the first Intel® XScale® technology-based processors to include Intel® Wireless MMX™ technology for high-performance media acceleration. Intel® Quick Capture technology provides one of the industry's most flexible and powerful camera interfaces for digital images and video. And while processor performance scales from 104 MHz up to a commanding 624 MHZ, the Intel PXA27x processor family provides a quantum leap forward in low power operation by incorporating Wireless Intel SpeedStep® technology. Finally, the Intel PXA27x processor is designed to make network transactions safer while helping to manage data security.

The Latest Processors:
AMD Athlon 64 FX-57, Intel Pentium
Pentium 4 670 D 820,

It took relatively long to prepare this material, as new processors kept being added to it in the process. We initially planned it as a review of the Pentium 4 670, but then we got hold of the Pentium D 820, and recently of a new single core flagship from AMD: Athlon 64 FX-57. However, despite the significant differences in positioning and performance, we still tried to bring tests of all the above mentioned processors together into a single article. Hopefully, it will have no effect on its content quality regarding each CPU. At first we are going to say a few words about each of the latest models.

Pentium 4 670

It's a logical successor to the Pentium 4 6xx series, one of its closest representatives is the previously reviewed Pentium 4 660. Thus, there is nothing special about it: the same core architecture (Prescott-2M) as in the Pentium 4 660, the same bus clock (800MHz in terms of bandwidth) and the L2 Cache size (2MB), but its clock has grown by another 200 MHz (i.e. up to 3.8 GHz). Judging from the latest (available in Internet) Intel's plans, the Pentium 4 670 must be the last processor in this line, as the 4GHz CPU based on Prescott-2M disappeared from the roadmap of this company last year. However, as Stephen King put it, "sometimes they come back"...

Athlon 64 FX-57

The renowned successor to Athlon 64 FX-55 acquired a new 90nm San Diego core (its differences from Venice are minimal) with an improved memory controller and SSE3 support. Besides, the clock has grown by another 200 MHz to reach 2.8 GHz. It's the first Athlon 64 FX manufactured by the 90nm process technology supporting SSE3. It's an indirect sign that this process technology is streamlined to manufacture flagship processors offering the highest performance. From the users' point of view, the new Athlon 64 FX is no different from the previous model: it is installed into the same CPU socket as the previous Athlon 64 FX-55 and makes no additional requirements to a motherboard.

CS 212 Computer Architecture

In Cs 212 In first and second trinal i have learn about how the computer work,the instrution set and about pipelining,and also in overclocking.But sometime this lesson is difficult to understand.
In this subject we discuss on how pipelining work in the computer and also on how we overclock the computer.We also discuss the different between the pipeline to the non-pipeline.
