RHPPC
The RHPPC is a radiation hardened processor based on PowerPC 603e technology licensed from Motorola (now Freescale) and manufactured by Honeywell. The RHPPC is equivalent to the commercial PowerPC 603e processor with the minor exceptions of the phase locked loop (PLL) and the processor version register (PVR). The RHPPC processor is compatible with the PowerPC architecture (Book I-III), the PowerPC 603e programmers interface and is also supported by common PowerPC software tools and embedded operating systems, like VxWorks. Technical details The RHPPC processor generates 190 MIPS with the Dhrystone mix with its core clock at 100 MHz (i.e. the RHPPC processor completes 1.9 instructions per cycle). The RHPPC runs with a 25, 33.3, 40, or 50 MHz 60x bus clock (SYSCLK) which is generated based on the PCI clock. The 60x bus clock is de-skewed on-chip by a PLL and can also be multiplied. The RHPPC processor is a superscalar machine with five execution units: system registe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiation Hardened
Radiation hardening is the process of making electronic components and circuits resistant to damage or malfunction caused by high levels of ionizing radiation (particle radiation and high-energy electromagnetic radiation), especially for environments in outer space (especially beyond the low Earth orbit), around nuclear reactors and particle accelerators, or during nuclear accidents or nuclear warfare. Most semiconductor electronic components are susceptible to radiation damage, and radiation-hardened (rad-hard) components are based on their non-hardened equivalents, with some design and manufacturing variations that reduce the susceptibility to radiation damage. Due to the extensive development and testing required to produce a radiation-tolerant design of a microelectronic chip, the technology of radiation-hardened chips tends to lag behind the most recent developments. Radiation-hardened products are typically tested to one or more resultant-effects tests, including total io ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
