A piece of DSP program want to do the following tasks
1)Use funcA() to process 1M bytes dataA and generate 2M bytes data B
2)Use funcB() to process 1M bytes dataA and generate 3M bytes data C
3)Move the data B generated in 1) external memory
Assume that Task1 needs 50ns and Task2 needs 60ns. QDMA is used in Task3
and the time needed for QDMA configuation and startup is 0.1ns.Data moving
for 2M bytes needs 40ns.
In order to finish the above tasks, whats the minimum time needed for this DSP program____. 展开

一片DSP程序要做以下tasks1)使用funcA()来处理字节dataA并产生2 m字节数据B2)使用funcB()来处理字节dataA并生成3 m字节数据C3)移动数据B中生成1)外部memoryAssume,Task1需要50 ns和Task2需要60 ns。QDMA用于Task3and所需的时间QDMA配制和启动是0.1奈秒。数据movingfor 2 m字节需要40 ns。为了完成上述任务,什么最小所需时间这DSP程序。
