Summary:
餘數系統的運算特性是無論在加法、減法以及乘法上都具有平行、無進位和快速的性質。然而,餘數系統對於正負符號的偵測、溢位的偵測、數值的比較和除法的運算就非常困難。其中,除法必須利用數值的比較,數值的比較架構於溢位的偵測,而溢位的偵測可由正負符號偵測來完成,然正負符號偵測可以靠奇偶校驗技術來驗證,因此,奇偶校驗技術是目前餘數系統最重要的課題之一。本論文主要是在餘數系統下,架構於一對模數組 {2p-j,2p+j},提出有效率的奇偶之校驗技術。給定一個餘數系統的數值 X={x_1,x_2},模數組 T={2p-j,2p+j},其中 j 為奇數和 p 為整數且滿足 p=(j+1)/2 mod j。在 x_1≥ x_2,且 (j+1)/2 和 p 為相異奇偶性質時,X 的奇偶判斷取決於 ⌊(((2j-1)x_1+x_2))⁄2j⌋ mod 2;反之,(j+1)/2 和 p 為相同奇偶性質時,X 的奇偶判斷取決於 x_1+x_2+⌊(((2j-1)x_1+x_2))⁄2j⌋ mod 2。又在 x_1 < x_2, 且 (j+1)/2 和 p 相異奇偶性質時,X 的奇偶判斷決定於 ⌊(((2j-1)x_1+x_2-1))⁄2j⌋ mod 2;反之,(j+1)/2 和 p 為相同奇偶性質時,X 的奇偶判斷決定於 x_1+x_2+⌊(((2j-1)x_1+x_2-1))⁄2j⌋ mod 2。 Residue Number System (RNS) has computational advantages for addition, subtraction and multiplication because of its properties of parallel, carry free, and high-speed arithmetic. But Residue Number System has computational problem for sign detection, overflow detection, number comparison and division. Division has to use with the number comparison. Number comparison is based on overflow detection. Overflow detection can accomplish the sing detection. Sing detection can confirm by parity detection technique. Therefore, parity detection technique is one of the most important issue in the Residue Number System. This paper discusses Residue Number System parity detection technique using two-moduli set {2p-j,2p+j}. Given an RNS number X={x_1,x_2 } based on the two-moduli set T={2p-j,2p+j },where j is odd and p is positive integer satisfying p=(j+1)/2 mod j . If x_1 ≥ x_2, (j+1)/2 and p are the different parity , it found that the parity of X is ⌊(((2j-1)x_1+x_2))⁄2j⌋ mod 2. On the contrary, (j+1)/2 and p are the same parity, that the parity of X is x_1+x_2+⌊(((2j-1)x_1+x_2))⁄2j⌋ mod 2. If x_1
