Abstract
The present disclosure provides a method and a system of verifying access by a multi-core interconnect to an L2 cache in order to solve problems of delays and difficulties in locating errors and generating check expectation results. A consistency transmission monitoring circuitry detects, in real time, interactions among a multi-core interconnects system, all single-core processors, an L2 cache and a primary memory, and sends collected transmission information to an L2 cache expectation generator and a check circuitry. The L2 cache expectation generator obtains information from a global memory precise control circuitry according to a multi-core consistency protocol and generates an expected result. The check circuitry is responsible for comparing the expected result with an actual result, thus implementing determination of multi-core interconnect's access accuracy to the L2 cache without delay.
