Abstract: A cross-domain device includes interfaces to couple to a first device, second device, and third device. The cross-domain device creates a first buffer in its shared memory to allow writes by the first device associated with a first software module and reads by the second device associated with a second software module, and creates a second buffer in the shared memory separate from the first buffer to allow writes by the first device associated with the first software module and reads by the third device associated with a third software module. The cross-domain device uses the first buffer to implement a first memory-based communication link between the first software module and the second software module, and uses the second buffer to implement a second memory-based communication link between the first software module and the third software module.

Abstract: Techniques for operating on an indirect memory access instruction, where the instruction accesses a memory location via at least one indirect address. A pipeline processes the instruction and a memory operation engine generates a first access to the at least one indirect address and a second access to a target address determined by the at least one indirect address. A cache memory used with the pipeline and the memory operation engine caches pointers. In response to a cache hit when executing the indirect memory access instruction, operations dereference a pointer to obtain the at least one indirect address, not set a cache bit, and return data for the instruction without storing the data in the cache memory; and in response to a cache miss, operations set the cache bit, obtain, and store a cache line for a missed pointer, and return data without storing the data in the cache memory.
