In-Datacenter Performance Analysis of a Tensor Processing Unit​

• lorenzhs 10y ago
  Figure 2 shows the floor plan; there's a large 256x256 8-bit matrix multiplication unit taking up nearly 1/4 of the die area, and the rest of the chip seems designed to feed it as quickly as possible. It operates at 700MHz and can do a vector-matrix multiplication (1x256 times 256x256) in a single cycle. Neat! It's a very simple CISC, so there's not a lot of control logic needed (only 2% of die area). Overall this is very clearly designed for Tensorflow.
