ADAPTIVE MATRIX MULTIPLIERS
Examples herein describe techniques for adapting a multiplier array (e.g., a systolic array implemented in a processing core) to perform different dot products. The processing core can include data selection logic that enables different configurations of the multiplier array in the core. For example, the data selection logic can enable different configurations of the multiplier array while using the same underlying hardware. That is, the multiplier array is fixed hardware but the data selection can transmit data into the matrix multiplier such that it is configured to perform different length dot products, perform more dot products in parallel, or change its output precision. In this manner, the same underlying hardware (i.e., the multiplier array) can be reconfigured for different dot products which can result in much more efficient use of the hardware.

HYBRID LIBRARY LATCH ARRAY
A static random access memory (SRAM) includes fast SRAM bit cells and fast multiplexer circuits that are formed in a first row of fast cells in a hybrid standard cell architecture. Slow SRAM bit cells and slow multiplexer circuits are formed in a second row of slow cells. The slow multiplexer circuits provide a column output for the fast SRAM bit cells and the fast multiplexer circuits provide a column output for the slow SRAM bit cells. Thus, one SRAM column has fast bit cells and slow multiplexer stages while the adjacent SRAM column has slow bit cells and fast multiplexer stages to thereby provide an improved performance balance when reading the SRAM.
