4/17/2024 0 Comments Moca test score 1530![]() Periodic spikes in the DPC latency indicate that there are poorly written drivers with ISRs that are taking way too long to execute. The result will be choppy audio.Ī 1,000 microsecond DPC latency is a bit high but the important part is that it's flat. If the sound card's sample buffer depletes before the DPC executes and refills it, then the sound card will have nothing to playback. The OS will execute the DPC at a priority level that is high, but not high enough to clobber more important interrupts. At that point, the ISR is done and the CPU can go back to its regularly scheduled programming. Both raw scores and corrected scores were analyzed but unless otherwise specifically stated, MoCA scores refer to raw scores. In order to keep the ISR as short and sweet as possible, all that the ISR does is create a DPC to refill the sound card's buffer. A standard procedure correction entails adding one point to the total score if the test taker has 12 years of education. The sound card will interrupt the CPU, and the CPU will execute an ISR in response to that interrupt. As this buffer runs down, it needs to be topped by the sound card's software driver. Group 3 comprised all of those individuals with a MoCA score of more than 26. They concluded that using lower cut points on the MoCA test may improve the test’s accuracy in. The middle two quartiles, where all individuals fell into the borderline cognitive impairment range (MoCA scores 2326), formed group 2. The researchers found that the MoCA test’s published cut off scores may be too high, resulting in significant overidentification of cognitive impairment, particularly in Spanish-speaking patients (an overall false positive rate of 79). ![]() Group 1 comprised all of those individuals with a MoCA score of less than 23. The MoCA is scored out of a possible 30 points, and the recommended threshold is 25/26 (26 and over indicating normal cognitive function). ![]() 1024 samples at 48,000 samples per second is enough for about 50 milliseconds of playback. The population was then divided into three test groups. DPCs are typically setup by interrupt service routines (ISR) so that they can be executed outside of the context of an interrupt.ĭPC Latency is a measure of how long the OS takes to execute a DPC once it has been created in the DPC queue.įor example, a sound card will typically buffer 128, 256, 512, or 1024 audio samples per channel at a time. ![]()
