The figure below shows how a given hardware module can execute concurrently from its producer and consumer modules in a dataflow fashion through the use of dependence FIFO queues, and single-reader/single-writer SRAM buffers.
Each module is connected to its consumer and producer via read-after-write (RAW) and write-after-read (WAR) dependence queues.

To minimize the footprint of micro-op kernels, while avoiding the need for control-flow instructions such as conditional jumps, the compute module executes micro-op sequences inside a two-level nested loop that computes the location of each tensor register location via an affine function.
This compression approach helps reduce the micro-kernel instruction footprint, and applies to both matrix multiplication and 2D convolution, commonly found in neural network operators.

Each data type can have a different integer precision: typically both weight and input types are low-precision (8-bits or less), while the accumulator tensor has a wider type to prevent overflows (32-bits).
In order to keep the GEMM core busy, each of the input buffer, weight buffer, and register file have to expose sufficient read/write bandwidth.

The Versatile Tensor Accelerator (VTA) is an open, generic, and customizable deep learning accelerator with a complete TVM-based compiler stack. We designed VTA to expose the most salient and common characteristics of mainstream deep learning accelerators. Together TVM and VTA form an end-to-end hardware-software deep learning system stack that includes hardware design, drivers, a JIT runtime, and an optimizing compiler stack based on TVM.
