摘要： A controller for controlling a dynamic random access memory (DRAM) comprising a plurality of blocks. A block is one or more units of storage in the DRAM for which the DRAM controller can selectively enable or disable refreshing. The DRAM controller includes flags each for association with a block of the blocks of the DRAM. A sanitize controller determines a block is to be sanitized and in response sets a flag associated with the block and disables refreshing the block. In response to subsequently receiving a request to read data from a location in the block, if the flag is clear, the DRAM controller reads the location and returns data read from it. If the flag is set, the DRAM controller refrains from reading the DRAM and returns a value of zero.

摘要： An apparatus includes a plurality of arithmetic logic units each having an accumulator and an integer arithmetic unit that receives and performs integer arithmetic operations on integer inputs and accumulates integer results of a series of the integer arithmetic operations into the accumulator as an integer accumulated value. A register is programmable with an indication of a number of fractional bits of the integer accumulated values and an indication of a number of fractional bits of integer outputs. A first bit width of the accumulator is greater than twice a second bit width of the integer outputs. A plurality of adjustment units scale and saturate the first bit width integer accumulated values to generate the second bit width integer outputs based on the indications of the number of fractional bits of the integer accumulated values and outputs programmed into the register.

摘要： An output buffer holds N words arranged as N/J mutually exclusive output buffer word groups (OBWG) of J words each of the N words. N processing units (PU) are arranged as N/J mutually exclusive PU groups. Each PU group has an associated OBWG. Each PU includes an accumulator and an arithmetic unit that performs operations on inputs, which include the accumulator output, to generate a first result for accumulation into the accumulator. Activation function units selectively perform an activation function on the accumulator outputs to generate results for provision to the N output buffer words. For each PU group, four of the J PUs and at least one of the activation function units compute an input gate, a forget gate, an output gate and a candidate state of a Long Short Term Memory (LSTM) cell, respectively, for writing to respective first, second, third and fourth words of the associated OBWG.

摘要： An output buffer holds N words arranged as N/J mutually exclusive output buffer word groups (OBWG) of J words each. N processing units (PU) are arranged as N/J mutually exclusive PU groups each having an associated OBWG. Each PU has an accumulator, an arithmetic unit, and first and second multiplexed registers each having at least J+1 inputs and an output. A first input receives a memory operand and the other J inputs receive the J words of the associated OBWG. Each accumulator provides its output to a respective output buffer word. Each arithmetic unit performs an operation on the first and second multiplexed register outputs and the accumulator output to generate a result for accumulation into the accumulator. A mask input to the output buffer controls which words, if any, of the N words retain their current value or are updated with their respective accumulator output.

摘要： A processor including a front end, at least one load pipeline, and a memory system that further includes a programmable prefetcher for prefetching information from an external memory. The front end converts fetched program instructions into microinstructions including load microinstructions and dispatches microinstructions for execution. The load pipeline executes dispatched load microinstructions and provides load requests to the memory system. The programmable prefetcher includes a load monitor, a programmable prefetch engine, and a prefetch requester. The load monitor tracks the load requests. The prefetch engine is configured to be programmed by at least one prefetch program to operate as a programmed prefetcher, such that during operation of the processor, the programmed prefetcher generates at least one prefetch address based on the load requests issued by the processor. The prefetch requester submits the at least one prefetch address to prefetch information from the memory system.

摘要： A microprocessor includes a predicting unit having storage for holding a prediction history of characteristics of instructions previously executed by the microprocessor. The predicting unit accumulates the prediction history and uses the prediction history to make predictions related to subsequent instruction executions. The storage comprises a plurality of portions separately controllable for accumulating the prediction history. The microprocessor also includes a control unit that detects the microprocessor is running an operating system routine and controls the predicting unit to use only a fraction of the plurality of portions of the storage to accumulate the prediction history while the microprocessor is running the operating system routine.

摘要： A hardware data compressor that compresses an input block of characters by replacing strings of characters in the input block with back pointers to matching strings earlier in the input block. A hash table is used in searching for the matching strings in the input block. A plurality of hash index generators each employs a different hashing algorithm on an initial portion of the strings of characters to be replaced to generate a respective index. The hardware data compressor also includes an indication of a type of the input block of characters. A selector selects the index generated by of one of the plurality hash index generators to index into the hash table based on the type of the input block.
