Drawing the concurrent scheduling diagram according the task cycle count, timing, and resource usage. 5. Modifying the code according to the scheduling diagram to realize the concurrent processing. 4.8Overall Optimization After the concurrent processing is done, the final tuning of the code can furthe...
Figure 6.2.PIC program timing: (a) instruction timing cycle; (b) BIN5 MPLAB simulation, showing output timing If the clock rate is known, the execution time for a section of code can be predicted. A frequency of 4MHz, using a crystal oscillator, is a convenient value as it gives an ...
Figure 6.Multicycle Custom Instruction Timing Diagram The processor asserts the active highstartport on the first clock cycle of the custom instruction execution. At this time, thedataaanddatabports have valid values and remain valid throughout the duration of the custom instruction execution. Thest...
From the local-memory read-modify-write-cycle timing diagram (Figure 12), the time from the falling edge of ALTCH to valid data on LAD is roughly Q3 + Q4; i.e., 2tQ. A more precise value can be obtained by using the table of output signal characteristics. The parameter of interest...
Referring to FIG. 12, a timing diagram shows cycle timing of a register indirect branch resolution and resteering of the instruction fetch unit502with respect to execution stages of a register indirect branch instruction. In the operand loading stage OP2of the branch, the instruction scheduling uni...
