Values can be obtained by the following equations, according to BLCK frequency. 2. Values can be obtained by the following equations, according to BLCK frequency and external bus cycles. 3. Values can be obtained by the following equations, according to BLCK frequency and external bus cycles. 4. Values can be obtained by the following equations, according to BLCK frequency and external bus cycles. 5. tc ns is added when recovery cycle is inserted. See Figure 5.2 |
