摘要： An output FIFO data transfer control device can comprise a geometric arithmetic core including one integer processing unit or IPU and a plurality of floating-point processing units or FPUs. Each processing unit includes an intermediate buffer or data output buffer for storing a data on an arithmetic result. When an instruction of data transfer from at least one of the plurality of processing units to one output FIFO is issued, a write/read pointer generating unit generates a write pointer identifying a specific location where data on an arithmetic result associated with the instruction is to be stored in the intermediate buffer of at least one of the plurality of processing units. The write/read pointer generating unit also generates a read pointer identifying a specific location where data is to be read out of the intermediate buffer of at least one of the plurality of processing units. A transfer mode setting unit sets a transfer mode identifying which at least one of the plurality of processing units is to transfer data on an arithmetic result, and sequentially furnishes a read enable signal to at least one of the plurality of processing units so as to read out the data from the intermediate buffer of at least one of the plurality of processing units.

摘要： A power operation device comprises a bit operation unit or performing a bit shift operation on a logarithmic base bit string from a logarithm operation unit according to an input exponent bit string Y, and for furnishing the shifted logarithmic base bit string as a multiplication bit string. An exponent checking unit checks whether or not the input exponent bit string Y is the ith power of a base 2 where i is an integer, and, if so, furnishes a selection signal to direct selection of the multiplication bit string from the bit operation unit. A multiplication bit string selection unit selects and furnishes the multiplication bit string when it receives the selection signal from the exponent checking unit. In contrast, the multiplication bit string selection unit selects and furnishes another multiplication bit string from a multiplier otherwise. An exponential operation unit performs a base-2 exponential operation on the selected multiplication bit string from the multiplication bit string selection unit, i.e., computes 2Z where Z is the selected multiplication bit string, and furnishes the computed base-2 exponential value as the power operation-result XY.
