www.ti.com SRIO Functional Description For posted WRITE operations, which do not require a RapidIO response packet, a core may submit multiple outstanding requests. For instance, a single core may have many streaming write packets buffered at any given time, given outgoing resources. In this application, the control/command registers can be release[...]

www.ti.com SRIO Functional Description Segmentation: The LSU handles two types of segmentation of outbound requests. The first type is when the Byte_Count of Read/Write requests exceeds 256 bytes (up to 4KB). The second type is when Read/Write request RapidIO address is non-64b aligned. In both cases, the outgoing request must be broken up into mul[...]
