  • This paper compares radix-2 based structures for 32768-point FFT. Radix-$2^k$ structures have been widely used because the butterfly is simple and the number of multipliers can be reduced in those structures. This paper applied various radix-$2^k$ structures to 32768-point FFT that is representing ultra-long FFT. The ultra-long FFT has been studied much recently. This paper shows that the radix-$2^4$ structure is the most adequate because it shows the smallest complexity in the synthesis and the best SQNR performance. should be placed here.

  • The Polygoni Radix and Cynanchi Radix have been used to potentiate the liver functions in clinic of Oriental Medicine. The water extracts of Polygoni Radix and Cynanchi Radix were administered orally to rats intoxicated with carbon tetrachloride and then this experiment have been performed by observing liver fatty degeneration and activities of enzymes such as cytochrome oxidase (CYO), adenosine triphosphatase (ATP), acid phosphatase (ACP), lactate dehydrogenase (LDH) and alkaline phosphatase (ALP). By oral administration of water extracts of the radices between 1 and 10 days, the following results were obtained. 1. The group given Cynanchi Radix extract showed recovery of the fat liver in 4 days, whereas that given Polygoni Radix extract did the recovery in 8 days. 2. In cytochrome oxidase activity, the group given Cynanchi extract showed normal activity in 6 days, whereas that given Polygoni Radix extract did the activity in 8 days. 3. In adenosine triphosphatase activity, the groups given Cynanchi Radix and Polygoni Radix extracts showed normal activities in 2 and 8 days, respectively. 4. In acid phosphatase activity, the groups given Cynanchi Radix and Polygoni Radix extracts showed recovery of the activities in 2 and 4 days, respectively. 5. In lactate dehydrogenase activity, the group given Cynanchi Radix and Polygoni Radix extracts showed recovery of the activities in 6 and 10 days, respectively. 6. In alkaline phosphatase activity, the group given Cynanchi Radix extract showed normal activity in 2 days, whereas that given Polygoni Radix extract showed slight recovery between 4 and 6 days followed by decrease of the activity in 8 and 10 days. From the above-mentioned results, it was found that both of the water extracts of Polygoni and Cynanchi Radix possessed the recovery action of liver function as intoxicated with carbon tetrachloride in rats. It is also noted that the extract of Cynanchi Radix showed more potent activity than that of Polygoni Radix.

  • The decoding of Turbo-Code relies on the application of a soft input/soft output decoders which can be realized using maximum-a-posteriori(MAP) symbol estimator[l]. Radix-2 MAP decoder can not be used for high speed communications because of a large number of interleaver block size N. This paper proposed a new simple method for radix-4 MAP decoder based on radix-2 MAP decoder in order to reduce the interleave block size. A branch metrics, forward and backward recursive functions are proposed for applying to radix-4 MAP structure with symbol interleaver. Radix-4 MAP decoder shall be illustratively described and its error performance capability shall be compared to conventional radix-2 MAP decoder in AWGN channel.

  • In this paper, an implementation method of RSA exponentiator based on Radix-$2^k$ modular multiplication algorithm is presented and verified. We use Booth receding algorithm to implement Radix-$2^k$ modular multiplication and implement radix-16 modular multiplier using 2K-byte memory and CSA(carry-save adder) array - with two full adder and three half adder delays. For high speed final addition we use a reduced carry generation and propagation scheme called pseudo carry look-ahead adder. Furthermore, the optimum value of the radix is presented through the trade-off between the operating frequency and the throughput for given Silicon technology. We have verified 1,024-bit RSA processor using Altera FPGA EP2K1500E device and Samsung 0.3$\mu\textrm{m}$ technology. In case of the radix-16 modular multiplication algorithm, (n+4+1)/4 clock cycles are needed and the 1,024-bit modular exponentiation is performed in 5.38ms at 50MHz.

  • In this paper, a Radix-8 structure for high-speed FFT is propose. Main block of the proposed FFT structure is Radix-8 DIF(Decimation In Frequency) butterfly. Even throughput of the Radix-8 FFT is twice than that of the Radix-4 FFT, implementation area of the Radix-8 is larger than that of Radix-4 FFT. But, implementation area of the proposed Radix-8 FFT was reduced by using DA(Distributed Arithmetic) for multiplication. For comparison, the 64-point FFT was implemented using conventional Radix-4 butterfly and proposed Radix-8 butterfly, respectively. The Verilog-HDL coding results for the proposed FFT structure show 49.2% cell area increment comparison with those of the conventional Radix-4 FFT structure. Namely, to speed up twice, 49.2% of area cost is required. In case of same throughput, power consumption of the proposed structure is reduced by 25.4%. Due to its efficient processing scheme, the proposed FFT structure can be used in large size of FFT like OFDM Modem.

  • Fast Fourier Transform is the fast implementation of Discrete Fourier Transform, which deletes periodic operation of DFT. According to the definition, radix-2 FFT can be implemented byre cursive call which divides the input signal points into 2 signal points. Because of its time-consuming stack-copy operation, this recursive method is very slow. To overcome this drawback, butterfly operation with signal rearrangement was devised. Based on the ideas of signal rearrangement and butterfly operation, this paper applies the signal rearrangement method to the Radix-3 FFT and checks the validity of this method.

  • Objectives : In order to distinguish morphological characteristics, because the inside portion of the root bark of Scutellariae Radix decomposes as time goes by, 2nd, 3rd, and 5th year Scutellariae Radix were sampled and compared according to their external, internal, and flour states through optical microscope. Methods : The slice of the tested material made by paraffin section technique was colored with Safranine Malachite Green contrast methods, and the flour of it was mounted by the liquid made by the same ratio of each of glycerin, acetic acid, and water, and then observed and photographed by olymphus-BHT. Results : 1. The inside of 2nd year Scutellariae Radix was rich and golden, the transverse section of Scutellariae Radix that was 3rd years of age was golden, but there were many Scutellariae Radix whose center portion turned redish brown, and the center portion of 5th year Scutellariae Radix had been decomposed or empty. 2. 2nd year Scutellariae Radix had the most starch grain, 5th year Scutellariae Radix had the least, and the middle portion of xylem that was 5 years of age had a cell ring that was corkish, but 2nd and 3rd year Scutellariae Radix did not have it. 3. In the flour state, 2nd, 3rd, and 5th year Scutellariae Radix did not have any difference, but the amount of starch grain was the most in 2nd year Scutellariae Radix and the least in 5th year Scutellariae Radix.
