Dual processor apparatus capable of burst concurrent writing of data
First Claim
1. A dual processor apparatus capable of burst concurrent writing of data employed in a communication system, comprising:
- two processors, one of said two processors being in active mode when the other is in standby mode, the processor in standby mode being operated in dependence on the control of the processor in active mode, with a central processing unit of the processor in active mode generating a dual request signal and providing a burst cycle allowing n data blocks to be continuously recorded with one row address strobe signal and n column address strobe signals to accommodate a storing of n data blocks in a dynamic memory inside of the processor in active mode during said burst cycle and transmitting the stored data and a corresponding address to said processor in standby mode each time the storing is executed; and
with the central processing unit of said processor in standby mode recognizing the start of the burst cycle concurrent writing when a dual request signal and a burst signal are received from said processor in active mode, and storing said data received from said processor in active mode in a corresponding position in accordance with the addresses received from said processor in active mode.

Abstract
A dual processor apparatus is capable of burst concurrent writing of data during a burst cycle in a communication system including two processors, one of which is in active mode, when the other is in standby mode. The processor in standby mode is operated in dependence on the control of the processor in active mode. In the apparatus, the central processing unit of the processor in active mode generates a dual request signal and provides a burst cycle, which can continuously record n data blocks with one row address strobe signal and n column address strobe signals, thereby storing n data blocks in a dynamic memory inside of the processor during the burst cycle and transmitting the stored data and corresponding addresses to the processor in standby mode each time when the storing is executed; and the central processing unit of the processor in standby mode recognizes the start of burst cycle concurrent writing if a dual request signal and a burst signal are received from the processor in active mode, and stores the data received from the processor in active mode in a corresponding position in accordance with the addresses received from the processor in active mode. The apparatus enhances reliability and improves performance in connection with the demand for data communication control by a routing processor controller used in super-high speed communication networks or for dualization for a main controller used in various communication networks.
