They also have two pairs of sensitive antennae that help detect movement in the water as well as chemicals transmitted through the water, such as that of a dead fish or a nearby potential mate. The Respiratory System of Crayfish. Crayfish do not have lungs, they use gills to gather oxygen and breath. The gills have a double set of leaf-shaped branches (in gill-chamber) and can be found on both sides of the carapace at the base of each walking leg (pereiopods). The gills can be identified as a fuzzy grey or brown organ.

IBM has PowerPC G5 dual-core processors ready

Apple Insider, citing an unnamed “Wall Street analyst”, reports that IBM is ready to take orders for the PowerPC 970MP (G5) dual-core microprocessor.

As you know, the company officially released information about these processors last month at the Power Everywhere Forum held in Japan. IBM representatives then said that Apple had access to prototypes of processors back in 2021 and could use them in new versions of Power Mac G5 desktop computers.

The microprocessor, codenamed Antares, is a 64-bit device containing two cores in a single die, each with its own L1 cache. In addition, the memory subsystem of each core includes 1 MB of L2 cache, which, according to the plan of the developers, should double the work efficiency compared to the current model IBM 970FX PowerPC G5. Several variants of the PowerPC 970MP will be released, according to IBM, operating at clock speeds from 1.4 to 2.5 GHz.

Earlier, an analyst at Caris & Company also reported that although customers for the new processor have not yet been announced, IBM confirms readiness for mass production. It has been suggested that the debut of new items in the new PowerMac G5 models will take place at the September Apple Expo in Paris.

Even before Apple announced the transition to Intel processors, there was information about the planned release of new PowerMac G5 models by the end of this year. More specifically, the release schedule for the high end models included two models built on two PowerPC 970MP processors (for a total of four processor cores). It is currently unclear if these plans were influenced by the decision to switch to another manufacturer’s processors. As a reminder, as a result of the last update of the PowerMac G5 line, only dual-processor models remained in it.
