An addressable high throughput multiply accumulator (AHT-MAC), including processing of data in row-major format where column-major is required or vice versa by multiplying a first argument by a second argument corresponding to an address in a memory to obtain a first result and adding the first result to a prior result having a prior address that matches the address corresponding to the first argument and the second argument while concurrently starting a multiplication operation in a second address.
