The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor. A CU typically uses a binary decoder to convert coded instructions into timing and control signals that direct the operation of the other units (memory, arithmetic logic unit and input and output devices, etc.).

The 68020 has many improvements over the 68000, including an instruction cache, and was the first Mac processor to support a paged memory management unit, the Motorola 68851. The Macintosh LC configured the 68020 to use a 16-bit system bus with ASICs that limited RAM to 10 MB (as opposed to the 32-bit limit of 4 GB).
Mac is a family of personal computers designed and marketed by Apple since 1984. The name is short for Macintosh (its official name until 1999), a reference to a type of apple called McIntosh.

[d] Control systems in advanced computers may change the order of execution of some ...
The hardware unit that performs the operation is known as a multiplier–accumulator (MAC unit); the operation itself is also often called a MAC or a MAD operation. The MAC operation modifies an accumulator a : a ← a + ( b × c ) {\displaystyle a\gets a+(b\times c)}
