Embodiment Construction
[0010] The specific embodiment of the utility model is described in detail below in conjunction with accompanying drawing.
[0011] In the present invention, considering the full utilization of the storage space, when the storage space is divided into two parts, the utilization rate of the storage space reaches the maximum, so the storage space is divided into two parts as an example for illustration.
[0012] As shown in Figure 1, the storage space is divided into two equal parts, that is, n=1.
[0013] In the case of conjugation, the filter coefficients processed by the ASIC chip have a total of 512 channels, which are stored in 16 built-in SRAMs respectively. According to a group of 2 blocks, a total of 8 groups, a total of 128K storage units, each storage unit has a word length of 32 bit. Based on the ASIC design idea, the 8 groups of coefficient storage spaces are divided into two parts, ie n=1.
[0014] As shown in Figure 2, the system starts to run. Firstly, the regis...
