Multi-Modal Systolic Array For Matrix Multiplication - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240220202 titled 'Multi-Modal Systolic Array For Matrix Multiplication

Simplified Explanation: The patent application describes a system and method for matrix multiplication using a systolic array that can be configured for different modes of operation.

• The systolic processor can handle different data types for matrix multiplication.
• For the first data type, the right-hand side data is loaded into the systolic array cells between row 0 and row m-1, while the left-hand side data is processed through the corresponding rows between rows 0 and m-1.
• For the second data type, each element of the left-hand side and right-hand side data is split into first and second element halves, which are then moved through the systolic array between rows 0 and 2m-1.

Key Features and Innovation:

• Configurable systolic array for matrix multiplication.
• Handling of multiple data types for efficient processing.
• Splitting elements for improved performance.

Potential Applications:

• High-performance computing.
• Scientific simulations.
• Image and signal processing.

Problems Solved:

• Efficient matrix multiplication.
• Handling of different data types.
• Improved processing speed.

Benefits:

• Faster matrix multiplication.

Original Abstract Submitted

a system and method for matrix multiplication using a systolic array configurable between multiple modes of operation. a systolic processor may receive a data type indicator for the matrix multiplication. for a first data type, the systolic processor may load the right-hand side data from the right-hand matrix register into the data processing cells of the systolic array between row 0 and row m−1, and pass the respective row of the left-hand side data through a corresponding row of the systolic array between rows 0 and m−1. for a second data type, the systolic processor may split each element of the left-hand side data and the right-hand side data into respective first and second element halves, and move each element half through a corresponding row of the systolic array between rows 0 and 2m−1.
