在双端口SRAM中实现同步硬件原语

Dual-port SRAM with Semaphore logic

在多处理器并行环境中,必须通过同步机制保证系统的一致性。硬件实现同步原语能大大减小系统开销,提高同步可靠性。本文介绍了如何在双端口SRAM中实现同步硬件原语,可在处理器不支持同步硬件原语的条件下提供可靠的同步机制。

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.
