• Latency: Number of clock cycles required for the function to compute all output values.
• Initiation interval (II): Number of clock cycles before the function can accept new input
data.
• Loop iteration latency: Number of clock cycles it takes to complete one iteration of the
loop.
• Loop initiation interval: Number of clock cycle before the next iteration of the loop
starts to process data.
• Loop latency: Number of cycles to execute all iterations of the loop.
- dct块小于(read_data、dct_2d和write_data)的nterval的总和。这意味着这些块是并行操作的。
- dct的时间间隔interval几乎与子块dct_2d的时间间隔相同。因此，dct_2d块是限制因素。
- dct_2d 中interval =latency ，因此内部块并没有并行操作
