Abstract:
A method for set-up of parameters needed in a write cycle for a CD-R or CD-RW system within a limited time interval, the method comprising:providing at least two consecutive time intervals, numbered m=1 and m=2, each containing at least six clock cycles; providing first and second, selected parameter value, stored in first and second registers, and providing third, fourth, fifth, sixth, seventh and eighth selected parameter values, stored in first, second, third, fourth fifth and sixth SRAMs; for a selected clock cycle of time interval number m=1, reading the first and second parameter values from the first and second registers, respectively, and reading the third parameter value from the first SRAM; for five selected clock cycles of time interval number m=2, reading the fourth, fifth, sixth, seventh and eighth parameter values from the second, third, fourth, fifth and sixth SRAMs, respectively; and during a sixth clock cycle that follows the five selected clock cycles within the time interval m=2: calculating a first selected linear combination of the first, third and fourth parameter values; calculating a second selected linear combination of the first, fifth and sixth parameter values; calculating a third selected linear combination of the second, seventh and eighth parameter values; placing the first, second and third linear combinations in third, fourth and fifth selected registers, respectively; reading new first and second parameter values into sixth and seventh selected registers, respectively; and reading a new third parameter value into a seventh SRAM.
