摘要： A system for computing an affinity for relocating a cell on a surface of a semiconductor chip is disclosed herein. The cell is located within a region and belongs to a net of cells. The system initially computes a weight associated with all cells in the net. The sytem then sums the weights of all cells in the net containing the cell for all cells located inside the region and at positions greater than and less than edges of the region and computes the affinity for moving the cell to points on the surface greater than, equal to, and less than the current position of the cell based on the weight sums from said summing function. The computing function further comprises combining the affinities determined based on weight sums with other affinities. The summing function further comprises computing a relationship between the amount of rows and columns of regions on the semiconductor chip surface, and the affinity computation function comprises combining the relationship with the weight sums.

摘要： A frequency reduction or phase shifting circuit has an input receiving an input data stream having an input frequency and a representation of desired output frequency. A splitter splits the input data stream into a plurality of split signals each at a frequency of the desired output frequency. A plurality of catchers identify valid bits of each respective split signal. A shifter shifts valid bits identified by at least some of the catchers by a predetermined number, which establishes a de-serialization level for frequency reduction or phase shifting. An output provides an output data stream at the desired output frequency.

摘要： A decoder for access data stored in n memories comprises a function matrix containing addresses of the memory locations at unique coordinates. A decomposer sorts addresses from coordinate locations of first and second m×n matrices, such that each row contains no more than one address from the same memory. Positional apparatus stores entries in third and fourth m×n matrices identifying coordinates of addresses in the function matrix such that each entry in the third matrix is at coordinates that matches corresponding coordinates in the first matrix, and each entry in the fourth matrix is at coordinates that matches corresponding coordinates in the second matrix. The decoder is responsive to entries in the matrices for accessing data in parallel from the memories.
