In a data storage system in which data words, including word check bytes and periodic block check bytes, are stored in failure independent modules, an improved ECC mechanism is incorporated which corrects words as they are accessed assuming random errors and logs the corrections. When a block check byte becomes available, the logged errors are sum compared with the block check byte to validate the...

An encoder (12) is disclosed for generating a cyclically encoded n-bit channel word from an incoming k-bit data word, the encoder comprising generator word and data word shift registers (4100 and 4200), input and buffer shift registers (4300 and 4400 to 4800) and gating and clocking means. For the encoder to function properly when the number of parity bits is small, one of the buffer registers is ...

PURPOSE:To obtain a device displaying a calculated result in any data format out of the one in a main storage part and the one proper to arithmetic processing by storing data in said data formats. CONSTITUTION:Data are stored in a register file memory by the 1st format corresponding to the data format in the main storage part and the 2nd format proper to the arithmetic processing. The data of the ...
