Latest Patents

One of Szarek's latest patents is titled "Computer system with a device for selectively blocking writebacks." This invention describes a computer system that includes a main memory and a writeback cache memory, along with an I/O device capable of data streaming. The memory controller in this system responds to signals indicating that the I/O device will perform a burst transfer of data to the main memory. It effectively blocks potential writebacks from the cache memory to the I/O device, preventing data overwriting from a flushed cache line. This innovation significantly increases system performance by allowing data from the I/O device to be written to the main memory without waiting for a snoop cycle and a writeback to be performed.

Another patent by Szarek is "Memory re-mapping in a microcomputer system." This invention involves a microcomputer system that has a first, low order address memory soldered to the planar printed circuit board, which can accept additional memory pluggable into a socket on the board. During the power-on self-test, the memories are tested, and if an error is detected in the first memory, it is disabled. The system then directs the lowest order memory addresses to the second memory while reducing the highest order addresses by the number of locations in the first memory.
