34 * This version of integer. c is for use on systems that have limited stack
35 * space and no display facilities. The complete version can be found in
36 * the Demo/Common/Full directory.
37 *
38 * As with the full version, the tasks created in this file are a good test
39 * of the scheduler context switch mechanism. The processor has to access
40 * 32bit variables in two or four chunks (depending on the processor). The low
41 * priority of these tasks means there is a high probability that a context
42 * switch will occur mid calculation. See flop. c documentation for
43 * more information.
44 *

47 /*
48 Changes from V1.2.1
49
50 + The constants used in the calculations are larger to ensure the
51 optimiser does not truncate them to 16 bits.
52
53 Changes from V1.2.3
54
55 + uxTaskCheck is now just used as a boolean. Instead of incrementing
56 the variable each cycle of the task, the variable is simply set to
57 true. sAreIntegerMathsTaskStillRunning() sets it back to false and
58 expects it to have been set back to true by the time it is called
59 again.
60 + A division has been included in the calculation.
