Ethos-N57

Specifications

Balanced inference efficiency and performance

Optimized for the most cost- and power-sensitive designs, Ethos-N57 delivers premium AI experiences in mainstream phones and DTVs. With the highest performance, an open-source software framework and the largest AI ecosystem, the Arm AI platform makes it easy to develop on Arm.

Key features

Balanced Performance
Delivers up to 2 TOP/s of performance using 1024 8-Bit MACs. 

Optimized Design
Drives up to 225% convolution performance uplift using Winograd on 3x3 kernels, delivering up to 90% MAC utilization.

High Efficiency
Internally distributed SRAM stores data close to the compute elements to save power and reduce DRAM access.

Futureproof
Supports a wide range of existing Machine Learning (ML) operations and future innovations through firmware updates and compiler technology.

Key benefits

The key benefits of Ethos-N57:

• Supports a variety of popular neural networks, including CNNs and RNNs, for classification, object detection, image enhancements, speech recognition and natural language understanding
• Reduces system memory bandwidth by 1.5-3x through clustering sparsity and workload tiling, with lossless compression for weights and activations on select networks
• Maximizes the number of parameters stored on-chip by storing compressed weights and activations in local SRAM and decompressing them on the fly
• Leverages sparse power gating techniques to reduce power by up to 50%
• Improves performance and extends battery life through intelligent data management techniques to minimize memory movement with up to 90% of accesses on chip
• Supports TrustZone system security to safeguard sensitive data with support for secure and non-secure modes
