In designing a computer’s cache system, the cache block or cache line size is an important parameter. Which of the following statements is correct in this context? A smaller block size implies better spatial locality A smaller block size implies a smaller cache tag and hence lower cache tag overhead A smaller block size implies a larger cache tag and hence lower cache hit time A smaller bock size incurs a lower cache miss penalty
