The physical memory of an system is organized as a sequence of 8-bit bytes. Each byte is assigned a unique address that ranges from zero to a maximum of 2^(32) -1 (4 gigabytes). programs, however, are independent of the physical address space. The opcode tables that follow aid in interpreting object code. Use the high-order four bits of the opcode as an index to a row of the opcode table; use the low-order four bits as an index to a column of the table. If the opcode is 0FH, refer to the two-byte opcode table and use the second byte of the opcode to index the rows and columns. The implements a LOADALL instruction capable of loading all visible machine state from an area in memory. The function of this instruction is the same as the LOADALL instruction [RASH]. Due to the architecture, and implementation of the , the format of the memory area used by the two processors is different.
