The placement and arrangement of the different components on a microprocessor chip is examined to mitigate the hot spots that may arise on the device during its operation. The power dissipation of the individual components on a microprocessor is spatially and temporally non-uniform, possibly resulting in high thermal gradients and, as a consequence, high thermal stresses. These hot spots arise because...
Register renaming and associated register management mechanisms represent a significant source of complexity in out-of-order micro architectures. We propose the use of register versioning to simplify this logic. Hardware-supported register versioning permits monotonically increasing version numbers to uniquely identify each uncommitted instance of an architectural register. Register versioning replaces...
Current microprocessors are effectively a system-on-a-chip, as they incorporate processing cores, interconnections, shared and private caches and DRAM controllers on a single die. Consequently, it is imperative to have fast and accurate simulation tools for such systems; this paper such a tool for simulating all current and announced variants of multicore processors that use the predominant PC (X86,...
