摘要： Presented herein is a direct memory access engine for providing data words in the reverse order. The data words are fetched in batches comprising a predetermined number of data words starting from the last data word and proceeding to the first data word. The batches are stored in a local buffer. The contents of the local buffer are transmitted in reverse order.

摘要： Presented herein are system(s), method(s), and apparatus for converting unsigned fixed length codes to signed fixed length codes. In one embodiment, there is presented a circuit for converting an unsigned code to a signed code. The circuit comprises a multiplexer. The multiplexer comprises a first input, a second input, and an output. The first input receives a first value, the first value being the right shifted unsigned code plus one. The second input receives a second value, the second value being an inverse of a right shifted unsigned code plus one. The output outputs a selected one of the first value received by the first input or the second value received by the second input. The multiplexer selects the selected one of the first value or the second value based on a least significant bit of the unsigned code.

摘要： Described herein is a method and system for multiplier optimization. A gate count savings that does not introduce additional quantization error can be achieved with this method and system. By increasing the number of digits in a multiplication result, partial products within a multiplication can be truncated. When the multiplication result is used in a subsequent operation, the gates required for the increased number of digits in the multiplication result can be made less than the gates saved within the multiply.

摘要： A system, method, and apparatus for dividing and truncating a dividend by a divisor, wherein the magnitude of the divisor is a positive power of two, e.g., 2x, is presented herein. If the divisor is positive, the sign bit of the dividend is concatenated x times and added to the dividend. If the divisor is negative, the dividend is inverted, the sign bit of the inverted dividend is concatenated x times, and added to the inverted dividend. The sign bit of the divisor is also added to the sum and the result is right shifted x times. If the signs of the divisor and the dividend are the same, a zero is shifted into the most significant bit during each right shift. If the signs of the divisor and the dividend are different, the most-significant-bit (sign bit) of the result of addition is shifted into the most significant bit during each right shift.
