points to an area of core whose length (in bytes) is given by After this call, the user’s program counter (pc) is examined each clock tick (60th second); is subtracted from it, and the result multiplied by If the resulting number corresponds to a word inside that word is incremented. The scale is interpreted as an unsigned, fixed-point fraction with binary point at the left: 177777(8) gives a 1-1 mapping of pc’s to words in 77777(8) maps each pair of instruction words together. 2(8) maps all instructions onto the beginning of (producing a non-interrupting core clock). Profiling is turned off by giving a of 0 or 1. It is rendered ineffective by giving a of 0. Profiling is also turned off when an is executed but remains on in child and parent both after a monitor (III), prof (I)
