|
fields:
|
|
(1) Instruction Name
|
|
(2) Instruction arguments description
|
|
(3) Description of the breakup of the opcode (1+7+8|8+8|1+4+4|1+7+1+3+4
|
|
|1+3+4+1+3+4|1+3+4+8|1+1+2+4+8)
|
|
(4) Architecture supported
|
|
|
|
The Register table is also defined. It contains the following fields
|
|
(1) Register name
|
|
(2) Module Number
|
|
(3) Module Index
|
|
(4) Opcode
|
|
(5) Regtype
|
|
|
|
The Memory access table is defined containing the various opcodes for
|
|
memory access containing the following fields
|
|
(1) Memory access Operand Name
|
|
(2) Memory access Operand opcode. */
