Title:
MULTI-MASTER-SWITCH-TYPE HIGH-SPEED INTERCONNECTION BACKPLANE BUS, CONTROL METHOD THEREFOR, AND PROCESSING SYSTEM THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/267318
Kind Code:
A1
Abstract:
Disclosed are a multi-master-switch-type high-speed interconnection backplane bus, a control method therefor, and a processing system thereof. The multi-master-switch-type high-speed interconnection backplane bus comprises: a programmable bus protocol controller. The programmable bus protocol controller is electrically connected to several processors of the processing system and several peripheral modules respectively. The programmable bus protocol controller receives control instructions of the several processors, and converts several processed one-to-one, one-to-many or many-to-one concurrent bus access into a virtual end-to-end connection by means of virtual address translation of the several peripheral modules corresponding to the control instructions, so as to improve the data transmission efficiency of the backplane bus. By using a star structure in which the programmable bus protocol controller is connected to the processors and the peripheral modules, the problem of bus resource limitation of concurrent access of multiple processors is solved, the data package collision rate is reduced, multiple processors are allowed to initiate bus access simultaneously or a single processor is allowed to initiate access of multiple peripheral devices simultaneously, and the multi-master access of the backplane bus achieves aggregation of multi-processor computing power.
