instruction storage การใช้

The two 18-bit base registers ( one for instruction storage and one for data storage ) permitted dynamic relocation : as a program got swapped in and out of main memory, its instructions and data could be placed anywhere each time it got reloaded.
;Instruction and data memories occupy different address spaces : For pure Harvard machines, there is an address'zero'in instruction space that refers to an instruction storage location and a separate address'zero'in data space that refers to a distinct data storage location.
Dataflow networks deliver the instruction tokens to the execution units and return the data tokens to the CAM . In contrast to the conventional von Neumann architecture, data tokens are not permanently stored in memory, rather they are transient messages that only exist when in transit to the instruction storage.
On the Larrabee and Xeon Phi also each have only one general-purpose integer register file, but the Larrabee has up to 16 XMM register files ( 8 entries per file ), and the Xeon Phi has up to 128 AVX-512 register files, each containing 32 512-bit ZMM registers for vector instruction storage, which can be as big as L2 cache.
