The plurality of registers is positioned between the plurality of execution stages to latch data between the plurality of execution stages.

Abstract: A processor includes an array of memory cells, a control module, a precharge circuit, and an amplifier module. The control module generates a clock signal at a first rate, reduces the first rate to a second rate for a predetermined period, and adjusts the second rate back to the first rate at an end of the predetermined period. The precharge circuit: based on the first rate, precharges first bit lines connected to memory cells in a first row of the array of memory cells; based on the second rate, refrains from precharging the first bit lines; and precharges the first bit lines subsequent to the end of the predetermined period. The amplifier module: based on the first rate, access first instructions stored in the first row; and based on the second rate, accesses second instructions stored in the first row or a second row of the array.

Abstract: A processor including a cache memory, a decoder, a precharge circuit, a control module, and an amplifier module. The decoder generates a first word line signal to access first instructions stored in a first word line, and (ii) generates a second word line signal to access second instructions stored in the first word line or a second word line. The precharge circuit (i) precharges first bit lines connected to the first word line prior to accessing each of the first and second instructions. The control module adjusts a rate of a clock signal from a first rate to a second rate. The amplifier module accesses the first instructions based on (i) the first word line signal and (ii) the clock signal at the first rate, and accesses the second instructions based on (i) the second word line signal and (ii) the clock signal at the second rate.

Abstract: A processor including a memory and a control module. The memory has an array of cells. The control module is configured to: determine a number of access cycles along a first word line; determine an extended period based on the number of the access cycles; generate a word line signal to maintain the first word line in an activated state during (i) an initial period and (ii) the extended period; and access a first cell during the extended period. The first cell is connected to the first word line. The control module is further configured to deactivate the word line and maintain the first word line in a deactivated state while accessing a second cell connected to the first word line. The accessing of the second cell is based on a bit line separation provided during the extended period.

Abstract: In one implementation, a pipeline processor is provided having a base architecture that includes one or more decoders operable to decode program instructions and generate one or more decoded instructions, and one or more execution units operable to execute the one or more decoded instructions. Each execution unit includes one or more execution pipeline stages. The pipeline processor architecture further includes one or more additional co-processor pipelines. The one or more decoders of the base architecture are operable to recognize one or more instructions to be processed by a given co-processor pipeline and pass the one or more recognized instructions to the given co-processor pipeline for decoding and execution.

Abstract: A processor includes a cache memory that has an array, word lines, and bit lines. A control module accesses cells of the array during access cycles to access instructions stored in the cache memory. The control module performs one of a first discrete read and a first sequential read to access instructions in a first set of cells of the array that are connected to a first word line and selectively performs one of a second discrete read and a second sequential read based on a branch instruction to access instructions in a second set of cells of the array that are connected to a second word line. The second word line is different than the first word line.

Abstract: A processor includes a cache memory. The cache memory includes an array of cells, word lines and bit lines. A control module enables a word line of the word lines to access a first cell in the enabled word line. The control module disables the word line and maintains the word line in a disabled state to access a second cell in the word line.

Abstract: A data processing system for executing a plurality of instructions having a prescribed program order comprises a register file, a reorder buffer, and a plurality of functional units. The register file includes a plurality of registers to store data. The reorder buffer includes N buffer locations of which M buffer locations are bypassable and N?M buffer locations are non-bypassable, wherein N and M are integers and N>M. Each functional unit is capable of executing instructions regardless of the prescribed program order. The reorder buffer temporarily stores data corresponding to the plurality of instructions. When data of one of the plurality of instructions to be executed by a corresponding one of the plurality of functions units is temporarily stored in one of the M bypassable buffer locations, the reorder buffer transfers the data in one of the bypassable M buffer locations to the corresponding one of the functional units in order to execute the instruction.
