A Radiation-Hardened AMBA Bus
It designed to meet the command- and data-handling requirements for missions requiring true space-grade radiation hardness and fault tolerance. The design uses parts with total-ionizing-dose tolerance appropriate for deployment on long-term missions in MEO or GEO environments. The design uses a space-quality dual-core processor ASIC, a field-programmable gate array (FPGA), memories, and interfaces to meet the command- and data handling requirements of medium-sized missions. Today’s system-on--chip (SOC) is designed with reusable intellectual property cores to meet short time to market requirements. This on-chip bus protocol is differentiated from other on-chip bus protocols with feature of efficient block data transfer. Embedded systems design focuses on low Power dissipation and system-on-chips. A reliable on-chip communication standard is a must in any SOC. The ARM Advanced Microcontroller Bus Architecture (AMBA) is an open-standard, on-chip interconnects specification for the connection and management of functional blocks in system-on a-chip (SoC) designs. It facilitates development of multi-processor designs with large numbers of controllers and peripherals. Keywords: AMBA,AHB,Difference of buses,radition hardened
