Figure 6 illustrates the percentage of unused prefetch
using various replacement schemes.
The mobile AMD Athlon 4 processor features QuantiSpeed architecture, which incorporates a nine-issue, fully pipelined superscalar micro-architecture, a superscalar floating-point unit, hardware data prefetch
, exclusive and speculative Translation Look-aside Buffers (TLB).
The centerpiece of the implementation is a single virtual worklist designed to enable physicians to read from anywhere, automatically prefetch
prior exams and patient information, and efficiently transmit images and cases between sites for consults or workload balancing.
Using a single-instruction prefetch
queue, eCOG1 boasts performance of up to 25 MHz to easily handle the 16-bit math that communications applications require.
Streaming SIMD Extensions (SSE) vector loops, and why vectorization is inhibited on non-vector loops -- Loops auto-parallelized for multi-core, and why parallelization is inhibited on serial loops -- Loops that are candidates for OpenMP parallelization -- Compute intensity of loops, and candidates for offloading to a GPU (Graphics Processing Unit) or accelerator -- Loops with very small or very large iteration counts, and how they can be modified to maximize performance for SSE and the cache-based memory hierarchy -- Data prefetching, and opportunities for prefetch
