And according to https://www.cpubenchmark.net/compare/4929vs5104/ARM-Cortex-A76-8-Core-1800-MHz-vs-ARM-Cortex-A55-8-Core-1800-MHz, at the same clock speed the A55 is actually *faster* than the A76 (CPUMark 3013 vs 2792) Perhaps the key phrase is, “...

And if it is like the ARM MMU which I am more familiar with, disabling the MMU also requires disabling the caches as well since the MMU controls the cachable properties of each mapped region. 👍 1 Member lupyuen commented Jul 15, 2024 • edited @henryrov It's possible that we...
参考译文:在RISC-V矢量ISA中,不是将向量长度固定在架构中,而是提供了一些指令(vsetvli、vsetivli和vsetvl),这些指令接受请求的大小并将向量长度设置为硬件限制和请求大小之间的最小值。因此,RISC-V提案更像是Cray的长向量设计或ARM的可扩展矢量扩展。也就是说,最多32个向量中的每个向量都具有相同的长度。[52]...
SiFive compares the Performance P550 core to Arm’s Cortex-A75 with higher performance in SPECint2006 and SPECfp2006 integer/floating-point benchmark, all a much smaller area which would enable a quad-core P550 cluster on about the same footprint as a single Cortex-A75 core. ...
(6). Furthermore, using values for caches of a processor with a different ISA does not impact AVF of caches in a significant way, as in [84] the AVF of caches for two different ISAs (ARM and x86) for 10 MiBench benchmarks shows that the difference is small.16 Table 2. Features ...
computer designers have a common goal: to find a language that makes it easy to build the hardware and the compiler while maximizing performance and minimizing cost and energy. This goal is time-honored; the following quote was written before you could buy a computer, and it is as true toda...
Hardware-supported trace interfaces like Intel PT and ARM ETM are commonly designed for offline analysis and offer detailed runtime insights [36], [37], [38]. While the traces are generated at program runtime, their analysis can be performed later (i.e., offline). Additional processing is ...
Going on for more than one year now is the effort for supporting KVM virtualization with the RISC-V architecture, which is very much important for RISC-V processors to be able to eventually take lift in the server space
Nevertheless, we have seen VLEN=128 SVE/SVE2 for cores from Cortex-A510 to Cortex-X2/X3/X4 and Neoverse (since it has been a mandatory requirement in ARMv9-A). SVE/SVE2 has claimed "Scaling single-thread performance to exploit long vectors" and is similar to RVV, which shares a simi...
