摘要： A controller is coupled to a plurality of registers arranged in an array having a physical configuration of N rows of registers and M columns of registers. A size register within the controller is provided for receiving a selected vector size parameter, which specifies a number of registers comprising a vector register. In response to the vector size parameter, columns in the register array are selected and concatenated to form a vector register having at least a number of registers equal to the vector size parameter. An offset parameter may be utilized to select columns that form a vector register from the M number of columns in the array. Multiple arithmetic logic units, where one arithmetic logic unit is coupled to each row of registers are utilized to perform vector operations. Any register in the array may be utilized to store a vector element or a scalar expression. Vector register lengths, and the number of vector registers, may be dynamically configured by setting the vector size parameter and the offset parameter in the controller.

摘要： In a data processing unit having a plurality of general purpose registers, an instruction is loaded. Such an instruction includes an operation, and at least one operand field, where the operand field specifies one of a plurality of base registers and a displacement value. To calculate a general purpose register address specified by such an operand field, the displacement value is added to a base value stored in a base register that is specified by a portion of the operand field. Finally, the data processing unit addresses a selected one of the general purpose registers, utilizing the calculated general purpose register address, for execution of the specified operation. Thus, the data processing unit is capable of addressing a larger number of general purpose registers than may be directly addressed utilizing a value represented by a limited number of bits within the operand field.

摘要： A vector having a plurality of elements is stored in an input storage area, wherein the vector elements are stored in a first pattern. Thereafter, the elements are transferred, in a first order, from the input storage area into a vector register interface unit. From the vector register interface unit, the elements are transferred to an output storage area and stored in addressable locations in one of a plurality of preselected patterns. The input storage area may be implemented with cache memory or a register array. The output storage area may be implemented with a cache memory or a register array. The first pattern in the input storage area may include alternating real and imaginary elements. The plurality of preselected patterns may include a reversed order pattern, or a separation of real and imaginary elements into two vector registers.

摘要： A single register file may be addressed using both scalar and SIMD instructions. That is, subsets of registers within a multi-addressable register file according to the illustrative embodiments, are addressable with different instruction forms, e.g., scalar instructions, SIMD instructions, etc., while the entire set of registers may be addressed with yet another form of instructions, referred to herein as Vector-Scalar Extension (VSX) instructions. The operation set that may be performed on the entire set of registers using the VSX instruction form is substantially similar to that of the operation sets of the subsets of registers. Such an arrangement allows legacy instructions to access subsets of registers within the multi-addressable register file while new instructions, i.e. the VSX instructions, may access the entire range of registers within the multi-addressable register file.
摘要翻译：可以使用标量和SIMD指令来寻址单个寄存器文件。也就是说，根据说明性实施例的多可寻址寄存器堆中的寄存器子集可以用不同的指令形式（例如标量指令，SIMD指令等）寻址，而整个寄存器组可以用另一形式的指令，这里称为矢量 - 标量延伸（VSX）指令。可以使用VSX指令形式在整个寄存器组上执行的操作集基本上类似于寄存器子集的操作集。这种布置允许传统指令访问多址寻址寄存器文件内的寄存器子集，而新的指令即VSX指令可以访问多址寻址寄存器堆中的整个寄存器范围。

摘要： Illustrative embodiments determine the data type of the operand being accessed as well as analyze the data value subrange of the input operand data type. If the operand's data type does not match the required format of the instruction being processed, a determination is made as to whether a subrange of data values of the data type of the input operand is supported natively. If the subrange of data values of the input operand is not supported natively, then a format conversion is performed on the data and the instruction may then operate on the data. Otherwise, the data may be operated on directly by the instruction without a format conversion operation and thus, the conversion is not performed.
