Data cache and direct memory access in programming mediaprocessors
D. Kim, Ravi Managuli, Yoochan Kim · IEEE Micro · 2001
Mediaprocessors provide high performance by using both instruction- and data-level parallelism. Because of the increased computing power, transferring data between off- and on-chip memories without slowing down the core processor's performance is challenging. Two methods, data cache and direct memory access, address this problem in different ways.
