  • Method and apparatus for DMA boot loading a microprocessor without an internal ROM
    Patent number: 6058474
    Abstract: A microprocessor 10 has an internal program memory 23 and direct memory access (DMA) circuitry 100. Microprocessor 10 also has provisions for connecting to an external source of data via an external bus 73. Configuration circuitry 74 or 81 provides configuration parameters to DMA 100 when a reset signal 76 is deasserted. DMA 100 boot loads microprocessor 10 by transferring a block of data which contains an initial program from an external source to internal program memory after reset signal 76 is deasserted. At the completion of the boot load, microprocessor begins execution of the initial program.
