None of the five engineering design teams could count on being able to bring about adjustments in architectural specifications as a way of easing difficulties in achieving cost and performance objectives.[1]: p.137 参考译文:在NPL(System/360)之前,公司的计算机设计师们不仅可以通过选择技术,还...
processor can execute these instructions directly. a software implementation, on the other hand, emulates the instruction set in software. this allows a processor to execute instructions that are not part of its native instruction set, but at a potential cost in performance. looking for a great ...
Our experiments show that such a strategy can effectively reduce the iTLB energy consumption by 81.3% on average with minimum impact on performance and hardware cost.doi:10.1166/jolpe.2006.061Allu, BramhaZhang, WeiDBLPJournal of Low Power Electronics...

A memory hierarchy consists of multiple levels of memory each using different devices for storing data and each having different speeds, capacities and cost associated therewith. Generally, the lowest-level of memory, commonly known as a cache, is coupled closely to the processor and uses ...
but it’s done in a different way. Instead of passing the head of a linked list of frames, theenterinstruction copies an entire array of pointers to frames. This reduces the number of instructions required in order to access faraway frames, but it increases the cost of a function call due...
using register-renaming hardware, may find it more convenient to expand C.MV to MV instead of ADD, at slight additional hardware cost. C.ADD adds the values in registers rd and rs2 and writes the result to register rd. C.ADD expands into add rd, rd, rs2. C.ADD is only valid ...
If the data is found in the cache, it enjoys the low retrieval delay, but if the data is preserved in DRAM, a higher latency cost is incurred to retrieve it [15]. A cache is divided into a series of blocks, also known as cache lines. A conventional cache line contains three ...
(ISA) as disclosed herein is expected to allow new programming models with reduced code size and overall system energy efficiency. The disclosed ISA addresses some of the unique challenges of exascale architectures. Exascale systems pose a complex set of challenges: (1) data movement energy cost ...
3. The constructive predicated variant shown in example 2 above incurs some cost in encoding space, which can be avoided by providing the destructive variant. Alternatively, a constructive unpredicated example could be provided to save on encoding three separate scalar registers: REP_ELEMENTS Zd, Zs...
