Dual-port SRAM with Semaphore logic
Jianguo Hu · Microcomputer Information · 2008
In the multiprocessors situation, synchronization mechanisms can prevent the system from reaching a nonconsistent state. And hardware-supplied synchronization primitives are a low-cost and reliable method to implement synchronization. This paper pre-sents a control logic to supply synchronization in a dual-port SRAM, which can supply synchronization in multiprocessors situation without synchronization instructions.
