Title: Coherency of i/o channel controller of data-processing system as well as apparatus and method for synchronization
Inventor: RABI KEI ARIMIRI
IPC: G06F12/08
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To obtain a more efficient IOCC design by not applying any I/O bus controller(IOBC) to a data cache and cache controller, but an I/O channel controller(IOCC) related to a system bus controller in the IOCC. SOLUTION: A system bus 108 and I/O bus 220 are connected to an IOCC 114 A system bus controller(SBC) 202 does not control any IOBC 201, but control a cache controller 203. Consequently, the SBC 202 offers the access to a DMA readout data cache or DMA write through data cache to the IOBC 201 at all times. Therefore, the SBC 202 can effectively execute system bus transfer. Because of the structure of the IOCC 114, system bus 108 searching operation generates an address particle size and the asynchronous handshake between the SBC 202 and IOBC 210 becomes the minimum.

Title: Detection circuit for majority decision error
Inventor: WATANABE FUYUKI
IPC: G06F11/18
Filed: 1989-09-28
Abstract: PURPOSE:To detect the error of the result of a majority decision by checking the coincidence of the combination of remaining logical signals excluding a logical signal where the error occurs in the first place in accordance with error information showing the logical signal where the error occurs in the first place. CONSTITUTION:When the error occurs in the logical signal 11 in the first place, an error display signal 14 outputted from an error check circuit 2 is stored in an error storage circuit 3. When error specification information 18 comes to '010', a selection circuit 7 selects a coincidence signal 16, and it is outputted as a valid/invalid signal 19. A coincidence detection circuit 5 checks the coincidence of the logical signals 10 and 12 and the coincidence signal 16 is outputted to the selection circuit 7. When the error occurs in either of the logical signals 10 or 12, the coincidence signal 16 comes to be '0', and the valid/invalid signal 19 comes to '0'. Then, the error is detected in the result of the majority decision 13 and it is shown as invalid. When the errors occur in two logical signals among three logical signals, the normality of the result of a majority decision judgement is maintained.
