Data acces in a RISC digital signal processor. |
摘要 |
<p>The STREAMER FOR RISC DIGITAL SIGNAL PROCESSOR shown herein allows a CPU 46 to interface with a memory 60 via data registers 50. Pre-fetch and post-store of the correct address is determined by an address generator 58 according to a rule determined by a context register 52. An index indicative of this address is stored in an index register 54. The data, context, and index registers together form a streamer 56, streaming data between the CPU 46 and data memory 60. The rule of the context register 52 also drives a converter 62 for converting data between memory format and register format. The speed and flexibility of a RISC device is combined with the intensive memory access of a digital signal processor.</p> |
