| 摘要 |
A digital signal processing system for executing instructions and processing data, including a program memory which stores encoded instructions, where the program memory (4) consumes less power when a bit having a first logical level is read therefrom than when a bit having a second logical level is read therefrom, and where the most commonly read encoded instructions comprise more (and preferably many more) bits having the first logical level than bits having the second logical level. Preferably, the program memory (4) is implemented as a read-only memory (ROM). Other aspects of the invention are a method for generating such encoded instructions and storing the encoded instructions in a ROM (4), a ROM which stores such encoded instructions, a digital signal processing system having a read-only program memory storing such encoded instructions, and methods for operating such a processing system.
