documented in Table 2 below, and will be encoded in software, to prevent a customer from exceeding it. This maximum will vary depending on the DSP processor speed, so a separate measurement will have to be done for SRMs containing faster processors. Due to system limitations, this number will never exceed 63. The number of ports supported for each of the Basic Services, per DSP processor, will be averaged (arithmetic mean) to create an average number of ports per DSP (Average_Ports_per_DSP). Because of the computational simplicity of the DTG Service, it will not be included in this calculation: Average_Ports_per_DSP = (#CPA + #DRC + #MFR1 + #MFCR2)/4 - -------------------------------------------------------------------------------- Service Predicted Measured Included in Maximum # Ports Maximum # Ports Average? - -------------------------------------------------------------------------------- DTG 63 To be measured Not included - -------------------------------------------------------------------------------- CPA 30 To be measured Included - -------------------------------------------------------------------------------- DRC 30 To be measured Included - -------------------------------------------------------------------------------- MFR1 30 To be measured Included - -------------------------------------------------------------------------------- MFCR2 30 To be measured Included - -------------------------------------------------------------------------------- TABLE 2. MEASURED PERFORMANCE OF SERVICES CAP: The runtime license fees is fully paid up after it reaches the CAP, which is the cumulative runtime license fees paid by LICENSEE for the first 75,000 processors as specified in Table 1 above. The CAP is cumulative across the Texas Instruments TMS320C54x, TMS320CSSx, and TMS320C6x, and other TI processors based on the same core processor architecture. BUYOUT OPTION: Within the Warranty period, LICENSEE may elect to pay D2 a sum of $1,400,000 as a one time paid-up runtime license fees for the Basic Services specified in Exhibit A.
