Use more CPU-efficient algorithms Defer or cache work Thread InterferenceCPU usage by threads that are not on the critical path (and that might be unrelated to the activity), can cause threads that are on the critical path to be delayed. The thread state model shows that this problem is ...

Our proposal is to optimize the OWM function, which is the most computationally intensive part of a reliable DTM algorithm proposed in [3], and to port it to GPU. More precisely, we present data structure and memory oriented optimizations that can be applied to other algorithms that process ...
Solving block-tridiagonal systems is one of the key issues in numerical simulations of many scientific and engineering problems. Non-zero elements are main
5.1. Reverse Engineering the Algorithms These algorithms are already present on the system. To generate similar outputs as they do, we studied and repurposed their code for simulation and monitoring. 5.1.1. Frequency Governor Frequency scaling is carried out by programs called Governors. In the st...
from the ROM160to boot the SoC100. The ROM160(e.g., boot ROM) is an integrated circuit that includes the code or codes (e.g., boot code) that are executed by the CPUSS105during an initial power-on or upon a watchdog reset condition. In some aspects, the ROM is enabled in firmw...
control unit (so that's up to 144 ops, which is significantly more than the P6's 40 entry reorder buffer) in addition to an 18 entry integer reservation station as well as a 36 entry FPU reservation station. Holy cow. The K7 will do an awful lot of scheduling for you, that's for...
