Transactional memory that performs a programmable address translation if a dat bit in a transactional memory write command is set

Abstract

A transactional memory receives a command, where the command includes an address and a novel DAT (Do Address Translation) bit. If the DAT bit is set and if the transactional memory is enabled to do address translations and if the command is for an access (read or write) of a memory of the transactional memory, then the transactional memory performs an address translation operation on the address of the command. Parameters of the address translation are programmable and are set up before the command is received. In one configuration, certain bits of the incoming address are deleted, and other bits are shifted in bit position, and a base address is ORed in, and a padding bit is added, thereby generating the translated address. The resulting translated address is then used to access the memory of the transactional memory to carry out the command.
