Clocking Scheme/Instruction
Cycle
The clock is internally divided by four to generate four
non-overlapping quadrature clocks, namely Q1, Q2,
Q3 and Q4. Internally, the PC is incremented every Q1,
and the instruction is fetched from program memory
and latched into the Instruction Register (IR) in Q4. It is
decoded and executed during Q1 through Q4. The
clocks and instruction execution flow is shown in
3.2
Instruction Flow/Pipelining
An instruction cycle consists of four Q cycles (Q1, Q2,
Q3 and Q4). The instruction fetch and execute are
pipelined such that fetch takes one instruction cycle,
while decode and execute takes another instruction
cycle. However, due to the pipelining, each instruction
effectively executes in one cycle. If an instruction
causes the PC to change (e.g., GOTO) then two cycles
are required to complete the instruction (Example 3-1).
A fetch cycle begins with the PC incrementing in Q1.
In the execution cycle, the fetched instruction is latched
into the Instruction Register in cycle Q1. This instruc-
tion is then decoded and executed during the Q2, Q3
and Q4 cycles. Data memory is read during Q2
(operand read) and written during Q4 (destination
write).

All instructions are single cycle, except for any program branches. These take two cycles, since the fetch instruction
is “flushed” from the pipeline, while the new instruction is being fetched and then executed.
