4 Hawk Programming Details Error Notification and Handling The Hawk ASIC can detect certain hardware errors and can be programmed to report these errors via the MPIC interrupts or the Machine Check Interrupt. The following table summarizes how the hardware errors are handled by the MVME5100 series: Table 4-3. Error Notification and Handling Cause Action Single-bit ECC Store: Write corrected data to memory Load: Present corrected data to the MPC master Generate interrupt via MPIC if so enabled Double-bit ECC Store: Terminate the bus cycle normally without writing to SDRAM Load: Present uncorrected data to the MPC master Generate interrupt via MPIC if so enabled Generate Machine Check Interrupt to the Processor(s) if so enabled MPC Bus Time Out Store: Discard write data and terminate bus cycle normally Load: Present undefined data to the MPC master Generate interrupt via MPIC if so enabled Generate Machine Check Interrupt to the Processor(s) if so enabled PCI Target Abort Store: Discard write data and terminate bus cycle normally Load: Return all 1s and terminate bus cycle normally Generate interrupt via MPIC if so enabled Generate Machine Check Interrupt to the Processor(s) if so enabled PCI Master Abort Store: Discard write data and terminate bus cycle normally Load: Return all 1s and terminate bus cycle normally Generate interrupt via MPIC if so enabled Generate Machine Check Interrupt to the Processor(s) if so enabled PERR# Detected Generate interrupt via MPIC if so enabled Generate Machine Check Interrupt to the Processor(s) if so enabled SERR# Detected Generate interrupt via MPIC if so enabled Generate Machine Check Interrupt to the Processor(s) if so enabled 4-6 Computer Group Literature Center Web Site
Endian Issues Hawk Endian Issues The MVME5100 series supports both Little and Big-Endian software. Because the PowerPC processor is inherently big endian, and PCI is inherently Little-Endian, it is easy to misinterpret the processing scheme. For that reason, provisions have been made to accommodate the handling of endian issues within the MVME5100. The following figures show how the MVME5100 series handles the endian issue in Big-Endian and Little- Endian modes: Big-Endian PROGRAM 60X System Bus N-way Byte Swap PCI Local Bus Hawk Big-Endian Figure 4-1.
