75 / 136 page  1996 Oct 29 75 Philips Semiconductors Objective specification GSM signal processing IC PCF5083 DB_copy_buffer n_words words are copied within DSP data RAM 27 source_buff_id dest_buff_id source_offset dest_offset n_words − DB_compare_info_cmi This procedure may be used to measure bit errors in a received burst. It compares the first n_bits soft outputs (CMIs) of the equalizer located in cmi_buff to the n_bits hard bits located in buffer info_buffer_id and returns the number of errors found (n_errors). 71 info_buff_ptr cmi_buff_ptr n_bits n_errors DB_fill_buffer n_words words are filled with fill_value. 28 buff_id buff_offset fill_value n_words − DB_pio_test This procedure can be used to test data transfer between the 90CL301 and the PCF5083. With every call, DB_pio_test checks if the parameters in_seq[0 to 4] are equal to the following predefined sequences of numbers: in_seq[0] = k × 3 in_seq[1] = k × 5 in_seq[2] = k × 7 in_seq[3] = k × 9 in_seq[4] = k × 11. Where k indicates how often DB_pio_test has been previously called (e.g. k = 0 for the first call after reset). The return value n_errors indicates the number of errors found in in_seq[0 to 4] (range 0 to 4). In addition the following predefined output sequences are returned: out_seq[0] = k × 11 out_seq[1] = k × 9 out_seq[2] = k × 7 out_seq[3] = k × 5 out_seq[4] = k × 3. 70 in_seq [0 to 4] out_seq [0 to 4] n_errors DB_read_buffer The n_words are read from buffer buff_id starting at offset buff_offset; n_words must not be greater than 19. 29 buff_id buff_offset n_words buff[n_words] DESCRIPTION ID PARAMETERS RETURN VALUES |
