What is parallel address space?
Submitted by: Muhammad☛ The two physically separate memories using the same addresses form the parallel address space.
☛ Here the two memories are accessed using different access modes.
☛ This parallel addressing is generally used in 8052(enhanced version of 8051) having extra 128 bytes of RAM with addresses 80 to FFH and memory is called as upper memory.
☛ This distinguishes it from lower 128 bytes 00to 7FH.
☛ To access lower bytes direct addressing mode is used and for higher bytes indirect addressing mode is used.
