Title: Low-complexity bit-parallel systolic multiplier over GF (2m)
Inventor: LEE CHIOU-YING
IPC: G06F7/44
Filed: 2001-11-02
Granted: 2003-04-11
Abstract: A low-complexity bit-parallel systolic multiplier over GF (2<m>) is disclosed. In the invention, two operation characteristics including cyclic shift and inner product operation are used, and a new algorithm capable of being used in the multiplication operation of GF (2<m>) is proposed. In accordance with the algorithm, a bit-parallel systolic multiplication circuit is designed. This bit-parallel systolic multiplication circuit is composed of n<2> identical basic units, in which m+1 <= N ≤ 2<M>-1. Each basic unit is provided with one two-input AND logic gate, one two-input XOR logic gate, and three registers. The computation delay of the multiplication operation is greatly reduced to n-pulse delay. If n is not much larger than m, for example m=4, 6, 8, 10, 11, 12, 18, 20, etc., the circuit framework can be a multiplier having very low complexity.

Granted: 2003-05-11
Abstract: The numerically controlled oscillator (8) is mounted in particular in a radiofrequency signal receiver which further includes means (3) for receiving and shaping the radiofrequency signals, a correlation stage (4) and a clock signal generator. The oscillator receives at one input a clock signal with a first frequency (CLK) which clocks the oscillator operations, and a binary word of several bits (Nb) to provide at one output at least an output signal (Mb) with a frequency determined as a function of said binary word and the clock signal. The oscillator includes a first accumulation stage (12) for a first number of most-significant bits (Ob) of the binary word and a second accumulation stage (12) for a second number of least-significant bits (Pb) of said binary word. The first accumulation stage is clocked at the first clock frequency (CLK) to supply the determined frequency output signal (Mb), while the second stage is clocked at a second clock frequency (CLK/N) N times lower than the first clock frequency. Output bits (Qb) or binary signals from the second stage are multiplied by N to be introduced at the input of the first stage every N cycles of the clock signal at the first frequency (CLK).

Title: Serial/parallel data converter and the conversion method
Inventor: CHIANG CHIN-YI
IPC: H03M9/00
Filed: 2002-04-12
Granted: 2003-07-11
Abstract: The present invention provides the improvement on the multiple clock phase circuit structure commonly used in the conversion from the high frequency serial data to parallel data for requiring more clock signals, wherein the required number of clocks is the bit width of the parallel data. This design can effectively reduce the required number of clocks, and for the setup time problem between the switching control signal for two sets of parallel data receivers and the clock signal of the first buffer for each data receiver, the present invention uses a pre-register in the circuit design. Because the pre-register does not need to conduct switching control, there is no such kind of setup time problem.
