The DAP 3000a is an excellent choice for applications where there is a need for a moderate amount of real-time processing of data in the time interval between samples, and for applications requiring fast sample rates.
The DAP 3000a/212 features a clock-doubled processor that executes two internal clock cycles for each external clock cycle. The 486 processor also features a hardware multiplier, making it well-suited for DSP operations. The processor used on the DAP 3000a/212 has a larger cache than that used on the DAP 3000a/111 which further improves the performance of the DAP 3000a/212.
The DAP 3000a models:
The 486 processor gives the DAP3000a low latency -- down to a 0.2 ms task time quantum. This means that when low latency mode is enabled, a single task will run for no more than 0.2 ms before DAPL switches to another task. This is crucial for process control applications where data must be responded to as quickly as possible.
