Abstract:
A system including a host coupled to a memory device and a peripheral controller device. The host is coupled to the peripheral controller device via a bus having a plurality of general purpose signal lines to carry time-multiplexed address, data, and control information. The peripheral controller device performs direct memory access (DMA) transactions with the memory device via the host and the bus.
Abstract:
TRUSTED INPUT FOR MOBILE PLATFORM TRANSACTIONS According to one embodiment, computer system is disclosed. The computer system includes a central processing unit (CPU), and a chipset coupled to the CPU including protected registers. The computer system also includes a micro-controller coupled to the chipset to perform scans to receive key-matrix data, wherein trusted software accesses the key-matrix data via the protected registers to ensure the authenticity of the data.
Abstract:
A system having a bus coupled to a host and a memory device. The bus may include a plurality of general purpose signal lines to carry time-multiplexed address, data, and control information. The memory device may store system start-up information and communicate this information with the host over the bus.
Abstract:
A system having a bus (124) coupled to a host (102) and a memory device (108). The bus (124) may include a plurality of general purpose signal lines to carry time-multiplexed address, data, and control information. The memory device (108) may store system start-up information and communicate this information with the host (102) over the bus (124).
Abstract:
A SYSTEM AND METHOD FOR PERMITTING THE EXECUTION OF SYSTEM MANAGEMENT MODE (SMM) CODE DURING SECURE OPERATIONS IN A MICROPROCESSOR SYSTEM IS DESCRIBED. IN ONE EMBODIMENT, THE SYSTEM MANAGEMENT INTERRUPT (SMI) MAY BE FIRST DIRECTED TO A HANDLER IN A SECURED VIRTUAL MACHINE MONITOR (SVMM). THE SMI MAY THEN BE REDIRECTED TO SMM CODE LOCATED IN A VIRTUAL MACHINE (VM) THAT IS UNDER THE SECURITY CONTROL OF THE SVMM. THIS REDIRECTION MAY BE ACCOMPLISHED BY ALLOWING THE SVMM TO READ AND WRITE THE SYSTEM MANAGEMENT (SM) BASE REGISTER IN THE PROCESSOR.
