A memory circuit for a print component including a plurality of I/O pads, including an analog pad, to connect to a plurality of signal paths which communicate operating signals to the print component. A memory component stores memory values associated with the print component, and a control circuit, in response to a sequence of operating signals on the I/O pads representing a memory read, provides an analog signal to the analog pad to provide an analog electrical value at the analog pad representing stored memory values selected by the memory read.

A computing device comprises two or more compute nodes, that each include two or more processor cores. Each compute node comprises an independently coherent domain that is not coherent with other compute nodes. A central IO die is communicatively coupled to each of the two or more compute nodes. A plurality of natively-attached volatile memory units are attached to the central IO die via one or more memory controllers. The central IO die includes one or more home agents for each compute node. The home agents are configured to map memory access requests received from the compute nodes to one or more addresses within the natively attached volatile memory units.

In one embodiment, a host controller includes: a first input/output (I/O) buffer to couple to a first communication line of an interconnect; a second I/O buffer to couple to a second communication line of the interconnect; and a device group selection circuit to dynamically cause the first communication line to communicate a clock signal to a first device group including one or more first devices to couple to the interconnect and dynamically cause the second communication line to communicate a data signal to the first device group when a communication is to be addressed to at least one of the one or more first devices of the first device group, such that the communication is transparent to at least another device group to couple to the interconnect. Other embodiments are described and claimed.

An apparatus includes a memory component having a plurality of ball grid array (BGA) components, wherein each respective one of the BGA components includes a plurality of memory blocks and a BGA component controller and firmware adjacent the plurality of memory blocks to manage the plurality of memory blocks. The apparatus further includes a processing device, included in the memory component, to perform memory operations on the BGA components.

Techniques are disclosed relating to an I/O agent circuit of a computer system. The I/O agent circuit may receive, from a peripheral component, a set of transaction requests to perform a set of read transactions that are directed to one or more of a plurality of cache lines. The I/O agent circuit may issue, to a first memory controller circuit configured to manage access to a first one of the plurality of cache lines, a request for exclusive read ownership of the first cache line such that data of the first cache line is not cached outside of the memory and the I/O agent circuit in a valid state. The I/O agent circuit may receive exclusive read ownership of the first cache line, including receiving the data of the first cache line. The I/O agent circuit may then perform the set of read transactions with respect to the data.

An input/output (I/O) write request directed at a plurality of memory devices having memory cells is received by a processing device. The write request includes a set of data. The processing device appends the set of data to a compound data object. The compound data object comprises one or more sequentially written data objects. The processing device associates the compound data object with one or more groups of memory cells of the plurality of memory devices. The processing device causes the compound data object to be written to the one or more groups of memory cells of the plurality of memory devices.

A universal floating-point Instruction Set Architecture (ISA) compute engine implemented entirely in hardware. The ISA compute engine computes directly with human-readable decimal character sequence floating-point representation operands without first having to explicitly perform a conversion-to-binary-format process in software. A fully pipelined convertToBinaryFromDecimalCharacter hardware operator logic circuit converts one or more human-readable decimal character sequence floating-point representations to IEEE 754-2008 binary floating-point representations every clock cycle. Following computations by at least one hardware floating-point operator, a convertToDecimalCharacterFromBinary hardware conversion circuit converts the result back to a human-readable decimal character sequence floating-point representation.

A universal floating-point Instruction Set Architecture (ISA) implemented entirely in hardware. Using a single instruction, the universal floating-point ISA has the ability, in hardware, to compute directly with dual decimal character sequences up to IEEE 754-2008 “H=20” in length, without first having to explicitly perform a conversion-to-binary-format process in software before computing with these human-readable floating-point or integer representations. The ISA does not employ opcodes, but rather pushes and pulls “gobs” of data without the encumbering opcode fetch, decode, and execute bottleneck. Instead, the ISA employs stand-alone, memory-mapped operators, complete with their own pipeline that is completely decoupled from the processor's primary push-pull pipeline. The ISA employs special three-port, 1024-bit wide SRAMS; a special dual asymmetric system stack; memory-mapped stand-alone hardware operators with private result buffers having simultaneously readable side-A and side-B read ports; and dual hardware H=20 convertFromDecimalCharacter conversion operators.

Technologies for cryptographic separation of MMIO operations with an accelerator device include a computing device having a processor and an accelerator. The processor establishes a trusted execution environment. The accelerator determines, based on a target memory address, a first memory address range associated with the memory-mapped I/O transaction, generates a second authentication tag using a first cryptographic key from a set of cryptographic keys, wherein the first key is uniquely associated with the first memory address range. An accelerator validator determines whether the first authentication tag matches the second authentication tag, and a memory mapper commits the memory-mapped I/O transaction in response to a determination that the first authentication tag matches the second authentication tag. Other embodiments are described and claimed.
