E xecution flow
System Architecture
Execution flow
The HT9480 system clock can be derived from
either a crystal or an RC oscillator. It is inter-
nally divided into four non-overlapping clocks
denoted by P1, P2, P3, and P4. E ach instruction
cycle consists of T1 to T4.
Instruction fetching and execution are pipe-
lined in such a way that a fetch takes an in-
struction cycle while decoding and execution
take the next instruction cycle. The pipelining
scheme causes each instruction to effectively
execute within a cycle. If an instruction changes
the content of the program counter two cycles
are required to complete the instruction.
Program counter – PC
The program counter (PC) is 13-bit wide and
controls the program ROM instruction se-
quence execution. The contents of the PC can
specify a of maximum 8192 addresses.
