3.27 Multiply and Accumulate Calculation Unit (MAC)
3.27.1
3.27.1.1 Control Register
64-bit arithmetic operations at high speed. The MAC has the following features:
The TMP92CF29A includes a multiply-accumulate unit (MAC) capable of 32-bit × 32-bit +

Reset State
Function
Note 1: <MOPST> is write-only and it is read as
Note 2: Writing “1xx” to <MSTTG2:0> and writing “1” to <MOPST> can be executed in the same write cycle.
Note 3: <MOVF> is fixed two system clocks (f
registers are connected to the CPU via a 32-bit bus and can be accessed in one system clock
(f
Registers
SYS
・ One-cycle execution for all MAC operations (excluding register access time)
・ Three operation modes :
・ Support for signed/unsigned operations
・ Support for integer operations only
The MAC in the TMP92CF29A has one control register and three data registers. These
).
The control register is used to control the operation of the MAC.
