The recent trend of Processing-in-Memory (PIM) promises to tackle the memory and energy wall problems lurking in the data movement around the memory hierarchy, like in data analysis applications. In this paper, we present our vision on how database systems can embrace PIM in query processing....
Processing-in-Memory (PIM) has been widely explored for accelerating data-intensive machine learning computation that mainly consists of general-matrix-multiplication (GEMM), by mitigating the burden of data movements and exploiting the ultra-high memory parallelism. The two mainstreams of PIM, the ...
忆阻器存算一体的工作步骤及简单代码模拟 | 忆阻器存算一体(Memristor-based Processing-in-Memory, PIM)在矩阵乘法中的计算流程大致如下: 1. 初始化忆阻器阵列: 忆阻器阵列中的每一个忆阻器都代表一个权重值,即矩阵A和B中的元素。首先,将矩阵A和B的元素值转换为对应的忆阻器状态(电阻值),并写入到忆阻器阵列...
在此过程中,q_input的尺寸为[1, emb_dim]。而k_input和v_input的尺寸为[n, emb_dim],代表到目前为止生成的所有前文token的嵌入向量。这个阶段的主要任务是计算当前生成的token与所有先前token之间的注意力关系。这个阶段更多的是 带宽密集型 向量乘以矩阵,就非常适合在PIM来做了。如下图: decoder 属于 GEMV...
Build a great PIM solution Through Process In Memory, we put an end to costly data movement by computing exactly where the data is: the memory. We developed the first PIM solution that is fully programmable, scalable, and efficient to address data-intensive applications and without requiring any...
(SIMD) execution units that uses the bank-level parallelism in PIM Block to boost performance that would have otherwise used multiple times of bandwidth from simultaneous access of all bank. The simulator include memory and have embedded within it a PIM block, which consist of programmable command...

Processing-in-memoryMachine learningNeural networksThe rising overheads of data-movement and limitations of general-purpose processing architectures have led to a huge surge in the interest in "processing-in-memory" (PIM) approach and "neural networks" (NN) architectures. Spintronic memories facilitate...
In normal memory mode, the PIM chips function as additional Sbus memory to the Sparc-2. In SIMD mode, the PIM chips accept commands from the Sparc-2 and execute those commands simultaneously on all PIM processors. Pairs of commands can be issued every 200 nanoseconds, giving an effective ...
