A streaming engine employed in a digital data processor specifies a fixed read only data stream. An address generator produces virtual addresses of data elements. An address translation unit converts these virtual addresses to physical addresses by comparing the most significant bits of a next address N with the virtual address bits of each entry in an address translation table. Upon a match, the translated address is the physical address bits of the matching entry and the least significant bits of address N. The address translation unit can generate two translated addresses. If the most significant bits of address N+1 match those of address N, the same physical address bits are used for translation of address N+1. The sequential nature of the data stream increases the probability that consecutive addresses match the same address translation entry and can use this technique.
