lookup-tables

问题 I am making a database for a freelance sign language interpreter. I have a subject table tblClient which holds information regarding the freelancer's clients. There is a lookup table tlkClient ClientType showing the various types of clients (categorized on condition -- deaf, deaf/blind, etc). There is also a table called tlkClient Modality. In this table are the different types of sign language offered by the interpreter. You can pick the client's preferred modality from the Client table. Now

问题 I want to calculate a 32-bit CRC lookup table. One way I tried is by using the following code from this website: #include <iostream> #include <stdint.h> void make_crc_table() { unsigned long POLYNOMIAL = 0x04c11db7; unsigned long WIDTH = 8 * sizeof(unsigned long); unsigned long TOPBIT = 1 << (WIDTH - 1); unsigned long crcTable[256]; unsigned long remainder; // Compute the remainder of each possible dividend for (int dividend = 0; dividend < 256; ++dividend) { // Start with the dividend

问题 I'm on the Intel Intrinsic site and I can't figure out what combination of instructions I want. What I'd like to do is result = high_table[i8>>4] & low_table[i8&15] Where both table are 16bits (or more). shuffle seems like what I want (_mm_shuffle_epi8) however getting a 8bit value doesn't work for me. There doesn't seem to be a 16bit version and the non byte version seems to need the second param as an immediate value. How am I suppose to implement this? Do I call _mm_shuffle_epi8 twice for

问题 This question already has answers here : SSE/SIMD shift with one-byte element size / granularity? (2 answers) How do I vectorize data_i16[0 to 15]? (1 answer) Closed 3 days ago . I'm trying to implement the strategy described in an answer to How do I vectorize data_i16[0 to 15]? Code below. The spot I'd like to fix is the for(int i=0; i<ALIGN; i++) loop I'm new to SIMD. From what I can tell I'd load the high/low nibble table by writing const auto HI_TBL = _mm_load_si128((__m128i*)HighNibble)

问题 I am trying to lookup a part number in a separate table array, the same value could be in multiple rows. The formula should find each instance of the value in the other table, move to a date column and determine which months the value exists in and which row it belongs to. The entire table B3:F15 should be automated. I have attached an image with proper explanation of what I am trying to accomplish if at all possible. The formulas would be entered into B3:F15. These are the cells where the
