Steve Munroe has posted an update to the “powerpc-cpu” project, which provides PowerPC optimizations for glibc. This update includes additional math library optimizations for POWER4 (and higher), POWER5+, and POWER6X. This version also includes a long double based slowpow (for double) implementation that is 30 X faster then the MPA-based implementation.

New PowerPCs from IBM

Oct 052006

IBM released two new PowerPC and announced some other stuff. First the new processors: 750CL and 970GX. Some refinements on previous models, but nothing too exciting. The 970GX is a single-core follow-on to the 970FX, runs up to 2.5 GHz, and doubles the L2 cache. The 750CL consumes even less power than previous 750s, and runs up to 1 GHz. Aside from the processors, the CPC965 970 northbridge will be available in March 2007, and there will be some new 32-bit 460 cores later in 2007.

Steve Munroe has posted another update to the “powerpc-cpu” project, which provides PowerPC optimizations for glibc. Version 0.03 includes general memmove and mpa optimizations based on gcc-4.1.1 loop unrolling plus a POWER6-tuned 32-bit memcpy. The mpa optimization improves the inner loop of log, exp, and pow.

Sep 132006

IBM has announced it now offers blades containing the Cell Broadband Engine (CBE) processor as a standard product, named QS20. As LinuxDevices notes, this is the second Cell blade available, the first being from Mercury Computing. Mercury of course is the high-end embedded company which bought Momentum, the company which made the “Maple” evaluation board for IBM’s PowerPC 970. It’s a small world…

IBM and Nintendo announced that the first “Broadway” PowerPC-based processors, which will power the upcoming Wii game console, are now shipping. Nintendo’s previous console, the GameCube, contained a PowerPC 750 derivative codenamed “Gekko”, so PowerPC is not as foreign to Nintendo as it was to Microsoft and Sony. For more information, Ars Technica has some in-depth speculation about Broadway.

IBM has released a new version of its XL compilers, which usually offer better optimization than gcc on IBM Power processors. The new versions are “IBM XL C/C++ Advanced Edition V8.0.1 for Linux” and “IBM XL Fortran Advanced Edition V10.0.1 for Linux,” and they both support Terra Soft’s Yellow Dog Linux distributions and Novell’s SLES10. 60-day demo downloads should be available shortly.

970FX Wins EEMBC Embedded Benchmark

Uncategorized Comments Off on 970FX Wins EEMBC Embedded Benchmark
Aug 212006

In a surprisingly technical press release, IBM announced yesterday that the 970FX rocked the TeleBench benchmark from the Embedded Microprocessor Benchmark Consortium (EEMBC, pronounced “embassy”). To be fair, most of the competition is sub-GHz embedded processors, and your editor hasn’t heard of many of them. The 2GHz 970FX approximately doubled the performance of Freescale’s 1.7GHz 7448 (“G4”), but no comparison was made regarding power consumption/heat dissipation or other real-world design factors.

Interestingly, while many of the processors benchmarked (including the 970FX) used Green Hills’ compiler, IBM also enhanced gcc’s autovectorization capabilities and ran with that. The results were huge.
