Q67000-H8627 on stock The PGIA 3606 allows the system user to modify and reprogram gain values for different analog input channels merely by changing the software computer program. Since different dedicated instruments are not required for various input channels, the PGIA also saves space and overall system costs. If the BURST signal is False when REQ is asserted at the beginning of an access, this is a single access and the machine goes to the bottom and cycles back around. An extra precharge clock cycle is needed at the end ofa memory cycle to ensure that no two accesses are too close. This is accomplished by waiting until all state bits go False before moving to the IDLE state. Once the state machine moves to IDLE, it can re-arbitrate. Because the IDLE cycle occurs before either RAS or CAS can be as- serted,this ensures that2 clock cycles are performed on back-to-back accesses with RAS False, which meets the precharge requirement. |
