Jul 132008

Wind River will release a technology preview of their new virtualization solution in August, supporting x86 and PowerPC processors. It will allow customers to run Linux, VxWorks, Windows, and other RTOSes simultaneously on the same system, even on a single core. The value? “Take advantage of the multi-core trend; integrate more features into their devices while leveraging existing code; isolate different functional system components; and consolidate hardware.”

As part of the QorIQ brand announced at Freescale Technology Forum this week, Freescale announced the e500mc core. The new P4080 processor contains eight 1.5GHz e500mc cores, while older e500v2 cores could be found in at most dual-core configurations. According to e500mc Linux patches also released this week, e500mc lacks SPE (the SIMD instruction set found on e500v1 and v2), but notably includes hardware hypervisor support, a first for embedded PowerPC.

Unpronounceable Freescale Rebranding

Uncategorized Comments Off on Unpronounceable Freescale Rebranding
Jun 172008

Freescale’s marketing folks have outdone themselves this time. While their core-to-chip numbering is mostly intelligible (e.g. 85xx chips use the e500 core), “PowerQUICC” generations have been a little more confusing. Now, in addition to PowerQUICC, they’ve introduced a new product line named “QorIQ” (pronounced “Core IQ”). Within the QorIQ line, there are five “platforms”, P1 through P5. Each platform encompasses multiple processors, so QorIQ P1 includes P1010, P1011, and P1020. Platforms 1 through 3 use and e500v2 (and maybe v1?) core, but P4 uses the new e500mc core, which can scale up to 8 cores on the P4080 processor. P5 is still a mystery.

AMD Promotes Accelerators; Criticizes Cell

Uncategorized Comments Off on AMD Promotes Accelerators; Criticizes Cell
Jun 062008

An AMD fellow presented to Stanford, promoting a vision of co-processor accelerators driven by a general-purpose core (which would also handle legacy and single-threaded tasks). However, although this is the basic design of the PowerPC-based Cell processor, he thinks an AMD x86 core surrounded by AMD/ATI graphics processing units (GPUs) is a better architecture.

Apparently the US Department of Defense is indeed discussing the P.A. Semi acquisition with both Apple and the Federal Trade Commission (which must approve the deal). Lots of comments from unnamed sources, but the 1682M chip is called a “very important and unique component,” which is a nice compliment even if it about to be end-of-lifed.

The news is a little old now, but VirtualLogix is apparently now supporting 750 and “PowerQUICC” processors with its embedded virtualization product. Although they have several flavors, including Digital Media and Mobile Handset, PowerPC support has only been added to the Network Infrastructure product. Further details, including pricing, availability, and how VLX uses privilege levels on PowerPC, don’t seem to be published.

Apparently the P.A. Semi acquisition was covered by a number of keynotes at the Critical Embedded Systems Conference, a conference about embedded systems in the military, and expectations range from optimism to pessimism about the future of P.A. Semi’s current Power Architecture processors. Ray Alderman from VITA confirmed the rumor that, due to their use in military systems, the U.S. goverment is working to “ensure continued supply” of PA6T parts.
