PEZY-SCnp (SC - Super Computer; np - New Package) is a revised version of the PEZY-SC model by PEZY introduced in may of 2016. The new chip, which made use of a slightly different package in order to address a number of signal-related issues (DRAM/PCIe signal failures). The new model uses a slightly larger package, lower core voltage, slightly higher core frequency, and thus higher performance. Operating at 766 MHz, the processor has a peak performance of 3.14 TFLOPS (single-precision) and 1.57 TFLOPS (double-precision). PEZY also upgraded the connections from PCIe Gen2 to Gen3. As with the PEZY-SC, the SCnp is also manufactured on TSMC's 28HPC+.
Architecture[edit]
- Further information: PEZY-SC § Architecture and PEZY-SCx § Architecture
The PEZY-SCnp's architecture is identical to the PEZY-SC.
Cache[edit]
PEZY-SC's cache is separate from the ARM926's cache which has an L1$ of 32 KiB (2x) and 64 KiB L2$ (shared).
Cache Organization
Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory. The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC. Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies. Note: All units are in kibibytes and mebibytes. |
