Operating Principles of MultiKron II Performance Instrumentation for MIMDComputers

摘要

The MultiKron II design is an enhanced version of our earlier MultiKronperformance instrumentation chip. They are both 179 pin chips, and although pin compatibility is close they are not 100% compatible. The MultiKron II has a longer TRACE sample, 20 bytes vs 16, to allow a larger user data and Timestamp fields. The 16 counters for resource utilization measurements are now writable, to allow for 'virtual' use, and their programming interface has changed to allow more options. Although designed for a 64-bit processor bus interface, an internal holding register provides for 32-bit mode operation.
