摘要： A method, computer program product, and data processing system for efficiently performing automated placement of timing-critical unit-level cells in a hierarchical integrated circuit design is disclosed. In preparation for global optimization the entire unit at the cell level, macro-level cells are assigned a “placement force” that serves to limit the movement of the macro-level cells from their current position. Movement boundaries for each macro element are also defined, so as to keep the components in a given macro element in relative proximity to each other. Optimization/placement of the unit design is then performed, via a force-directed layout algorithm, on a “flattened” model of the design while respecting the movement boundaries. Following this “flattened” optimization, the placed “unit-level” cells are modeled as blockages and the macro elements are optimized individually, while respecting the location(s) of the blockages. This entire process is repeated until the optimization of the unit layout eventually converges.

摘要： Embodiments relate to packed loading and storing of data. An aspect includes a system for packed loading and storing of distributed data. The system includes memory and a processing element configured to communicate with the memory. The processing element is configured to perform a method including fetching and decoding an instruction for execution by the processing element. A plurality of individually addressable data elements is gathered from non-contiguous locations in the memory which are narrower than a nominal width of register file elements in the processing element based on the instruction. The processing element packs and loads the data elements into register file elements of a register file entry based on the instruction, such that at least two of the data elements gathered from the non-contiguous locations in the memory are packed and loaded into a single register file element of the register file entry.

摘要： Mechanisms are provided for dynamic data driven alignment and data formatting in a floating point SIMD architecture. At least two operand inputs are input to a permute unit of a processor. Each operand input contains at least one floating point value upon which a permute operation is to be performed by the permute unit. A control vector input, having a plurality of floating point values that together constitute the control vector input, is input to the permute unit of the processor for controlling the permute operation of the permute unit. The permute unit performs a permute operation on the at least two operand inputs according to a permutation pattern specified by the plurality of floating point values that constitute the control vector input. Moreover, a result output of the permute operation is output from the permute unit to a result vector register of the processor.

摘要： Mechanisms for aligning enhanced precision vectors based on reduced precision data values are provided. At least one data value, having a first precision type, is received for storing in a vector register. The vector register stores data as a vector having a plurality of vector elements. The first precision type is modified to have a second precision type different in precision than the first precision type to thereby generate at least one modified data value. The at least one modified data value is stored in at least one vector element of the plurality of vector elements. An alignment of the at least one modified data value is determined relative to a boundary of a vector element of the vector register. An alignment operation to re-align the at least one modified data value based on the boundary of the vector element of the vector register is performed.
