Explanation:

Control signals are of two types: clocks and signals that set up communication channels and control the flow of data. Clock signals will be discussed later; only the latter type of control signals is discussed in this section. Since this class of architectures is strongly coordinated, control circuits can be distributed to the PEs and RAMs. Figure 9.25 shows how the control circuits can be distributed.

Each RAM receives its addresses from an associated ROM which contains successive read and write addresses. In practice, several ROMs can share the same address decoder. The ROMs are addressed by a counter which sequences through all values. The RAMs also receive a read and write signal every other cycle. The ROMs also contain information about which RAM the outputs of the PEs shall be stored into.
