因为大部分场景下我们会将其固定为一个常值,通常这个常值等效为AXI总线的位宽。比如16Byte的总线,那么AxSize通常设置为4即2^4 = 16;同理32Byte的总线则设置为5。翻开AXI5协议中关于AxSized说明,其描述的是每一笔transfer的byte数量,当然了一笔transaction的每个transfer占据的位宽必须是一致的,所以Size在Ax通道中...
• 当本次传输的突发宽度 (AxSIZE) 小于通道本身的宽度 (假设为 size) 时,这次传输被称为窄传输 – 数据在通道上传输的位置必须与 (数据的地址) % size 保持一致 • AXI4 规定: – master 必须保证 WSTRB 只在对应字节有效时为高 (1)示例1 (2)示例2 6. 非对齐传输 非对齐传输 起始地址AxADDR与突...

Currently, wide reads will access all sub-banks of the wide memory bank, even if not needed as specified in the AXI size field. While minimal, this can lead to more contention with narrow banks.micprog added the enhancement label Aug 22, 2024 ...
注:以下文字只是针对AXI full,对于lite 和stream需自行考虑后再决定适不适用!(1)在这只想讲明AXI协议中axsize(awsize和arsize)和axlen(awlen和arlen)的关系。我们都知道AXI协议是针对burst的突发形式的。AXI4支持burst的大小(值)为1,2,4,8,16,32,64,128,256.Axlen就等于burst的值 减1。(表示一个burst总...
axi read interleave size概念 Axi read interleave size refers to the number of data transfers that can be initiated concurrently on an AXI (Advanced eXtensible Interface) bus during a read operation. The interleave size is a configurable parameter thatdetermines the level of concurrency or parallelism...

Because a small Max Burst Size reduces speed, you may pad your data to fill a multiple of a larger number. I suppose 32bit is define in AXI-stream right? The standard DMA has widths of 8, 16, 32, 64, 128, etc. bits but AXI-stream spec, afaik, doesn't impose that restriction....
