Latest Patents
Kin-Ling Cheung holds a patent for a "Memory address generator with device address type specifier." This invention pertains to an address generating apparatus designed for use in a computer system that includes a bus processor, a memory requiring 24-bit addresses, and multiple I/O processors. Some of these processors generate 22-bit addresses while others generate 24-bit addresses on a system bus connecting them with the memory. The apparatus introduces a 2-bit prefix to the address on the system bus when the address originates from a 22-bit device. The 22-bit devices are specified by a mask register, and the prefixes are managed by a set of prefix registers, one for each device. The system's bus grant logic determines which device controls the system bus, while the address generating apparatus checks the mask register to see if a prefix is needed. If required, the apparatus outputs the device's prefix to the two most significant address lines of the system bus simultaneously with the 22-bit address to the remaining address lines. The mask and prefix registers can be loaded from the bus processor via a bus independent of the system bus. During system initialization, the bus processor loads the mask register as necessary for the I/O devices, and during operation, it loads prefixes for 22-bit devices as needed.
