摘要： A circuit designer may use computer-aided design (CAD) tools to implement an integrated circuit design. The CAD tools may include auto-pipelining capabilities to improve the performance of the integrated circuit design. Auto-pipelining may modify the number of pipeline registers in a path within a given range. A description of the integrated circuit design may include different implementation alternatives of a path each having a different number of pipeline registers, and the CAD tools may select one of these implementation alternatives. The CAD tools may further evaluate the performance of a particular implementation alternative and iteratively select a different implementation alternative until a given objective is met. The CAD tool may update a test environment according to the selected implementation alternative once the objective is met and validate the selected implementation alternative using the updated test environment.

摘要： TDM circuitry that includes a rotary multiplexer and a memory circuit is provided. A first rotary multiplexer circuit may receive N-bit wide data in accordance to a time division multiple access (TDMA) scheme. The N-bit wide data includes multiple sets of M-bit wide data. The first rotary multiplexer may rotate these sets of the M-bit wide data. The memory circuit is coupled to the first rotary multiplexer circuit. The memory circuit stores each of rotated set of M-bit wide data. A second rotary multiplexer circuit may read k-th bits of the each of the stored M-bit wide data from the memory circuit and may rotate these k-th bits before outputting these k-th bits serially, where k is an integer having a value greater than 0.

摘要： Methods and systems for encoding and decoding data using a streaming product-code (SPC). An SPC codeword has a first and second portion in a first and second component stream of the SPC, respectively. The first portion of the first codeword is arranged along a first dimension of the SPC, and the second portion of the first codeword is arranged along a second dimension of the SPC. The SPC efficiently encodes data into a desired target frame format without the overhead of dedicated mapping logic used by product-codes solutions.
