Movidius upgrades VPU with on-chip neural compute
Video processor company Movidius, now a subsidiary of Intel, has introduced its third generation of Myriad VPU with an on-chip neural compute engine - a dedicated hardware accelerator for deep neural network inferences.

Although Movidius has not said what manufacturing process the Myriad X is implemented in it does claim that it is capable of delivering an aggregate performance of over 4 trillion operations per second (TOPS) and that this makes the chip sufficiently power efficient to perform vision and artificial intelligence applications within drones, smart cameras, smart home, security, VR/AR headsets, and 360 cameras. The neural compute engine is a capable of 1 TOPS of compute performance on deep neural network inferences.

The neural compute engine comes with 16 SHAVE vector processor cores the MyriadX includes additional upgrades to imaging and vision engines including additional programmable SHAVE cores, upgraded and expanded vision accelerators, and a 4K ISP pipeline with support for up to 8 HD sensors connecting directly to the VPU.

As with Myriad 2, the Myriad X VPU is programmable via the Myriad Development Kit (MDK) which includes development tools, frameworks and APIs to implement custom vision, imaging and deep neural network workloads on the chip.

The Myriad 2 VPU was capable of running neural networks and indeed it was this capability that led to its introduction of the Fathom Neural Compute Stick, based on its Myriad 2 vision processor in 2016 (see Movidius shows neural network stick). The Myriad X VPU extends this capability so that it can reach 10X the performance for applications that require multiple neural networks running simultaneously, the company said.
