Vector Engine Type 10B is an octa-core vector processor designed by NEC and introduced in late 2017. This chip is fabricated on TSMC 16 nm process based on the SX-Aurora mircoarchitecture. VE Type 10B operates at 1.4 GHz and comes with 48 GiB of six 8-hi stacks of HBM2 memory.


The Vector Engine Type 10B operates at 1.4 GHz and integrates eight vector cores.

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.
