2021年3月2日 · The RAD750 comes in two versions: "rad-tolerant" and "rad-hardened". According to a quote in this question, InSight used the rad-hardened version. BAE (the manufacturer of the RAD750) says very little about how their products are radiation-hardened, but does like to tout that they are hardened.

2021年3月5日 · Radiation hardened CPUs like RAD750 are radiation hardened for up to 1000 gray. Cool.But, as CPUs have advanced way ahead their mechanical counterparts in miniaturization and fragility, energy dissipation and costs per kg to orbit have lowered, wouldn't just a simple lead shield start being more economic?.

2021年6月23日 · The Curiosity and Perseverance rovers, and the InSight lander, all use the BAE RAD750 processor. The Ingenuity helicopter uses a Qualcomm Snapdragon 801 processor. The only other active spacecraft on the surface of Mars is …

2022年7月15日 · The widely-used RAD750 is kinda-sorta like a PowerPC, but compared to a 1998 PowerPC (which was desktop state of the practice 24 years ago, not even state of the art), a RAD750 runs at half the clock speed, has very limited main memory, and has even more limited cache memory. $\endgroup$ –

2022年9月10日 · Just stumbled across RAD750s successor, the RAD5500. Are there already spacecraft using this Chip, or are there plans for this chip? Looks pretty new!

The RAD750 is a radiation-hardened single board computer manufactured by BAE Systems Electronics, Intelligence & Support. The successor of the RAD6000, the RAD750 is for use in high radiation environments experienced on board satellites and spacecraft. The RAD750 was released in 2001, with the first units launched into space in 2005.

2022年9月10日 · What makes Insight's RAD750 processor so radiation resistant? (compared to 1998 iMac's PowerPC 750) Gizmodo's A 1990s iMac Processor Powers NASA’s Perseverance Rover references NewScientist and says: However, there’s a major difference between the iMac’s CPU and the one inside the Perseverance ...

The processing power in current exploration rovers like the MER's RAD6000 (20Mhz) and Curiosity's RAD750 (200Mhz) is far below anything you would find in any mobile phone today. As far as I understand this is mainly due to the radiation hardening and possibly temperature ranges.

2020年4月29日 · The JWST uses one RAD750 clocked at 118 MHz which is based on the PowerPC 750. Not sure if JWST uses the 3U or 6U version. Below is the CPU architecture for the 6U from this thesis. This report contains a table of processors. Slides 59 and 60 might be of interest to you too. They discuss the SW layers, components, and flight software "app store".

However, the chip that was used, the RAD750, has years of experiments and usage behind it, such as being used in a variety of spacecraft including: Deep Impact comet chasing spacecraft, launched in January 2005 - first to use the RAD750 computer.
