Abstract
Circuitry for use in operating on block floating-point data where all data in a block has a scale factor associated therewith including a maximum scale register for storing the maximum scale factor of the data in a block, a subtractor for obtaining a difference value between the maximum scale factor and a data scale factor as the data is retrieved for operation, and a computer for adjusting the scale of retireved data by the difference prior to operation on the data. As the data in a block is operated on scale overflow is stored and used to adjust subsequent data as read from memory prior to operation thereon. A counter is provided for counting all scale overflow as a result of operations on all data in a block with the maximum scale register being updated based on the total count following operations on all data in the block.
