Abstract: A processor includes a time counter and provides a method for statically dispatching instructions with preset execution times based on a time count from the time counter provided to an execution pipeline.
Abstract: A processor includes a time counter and at least one execution slice that is comprised of an instruction decode unit, a time-resource matrix unit, an issue unit, an execution queue, and a functional unit. An instruction is issued to the execution queue to execute at a future time depending on the availability of resources specified in the time-resource matrix, wherein the future time is a time defined by a time count from a periodically incremented time counter.
Abstract: A processor includes a plurality of register sets of a register file, and a plurality sets of functional units which are coupled by sets of dedicated read and write buses to allow parallel execution of instruction. The register sets and functional units are organized as odd and even sets. Shared buses may also be employed. The processor may also include a time counter and a time-resource matrix and provides a method for statically dispatching instructions.
Abstract: A processor includes a time counter and a time-resource matrix and statically dispatches baseline and extended instructions. The processor includes a plurality of register sets of a register file and a plurality of sets of functional units which are coupled by sets of dedicated read and write buses to allow parallel execution of baseline and extended instructions.
Abstract: A processor includes a time counter and a register scoreboard and provides a method for statically dispatching custom or extended instructions with preset execution times based on a write time of a register in the register scoreboard and the time counter provided to an execution pipeline.
Abstract: A processor includes an instruction issue unit that receives a first instruction, and issues the first instruction with a write time, which for a load instruction corresponds to a data cache latency time or to a non-cacheable latency time of a non-cacheable predictor. The non-cacheable predictor includes a tag array and data array with a plurality of entries to predict non-cacheable latency times of non-cacheable load instructions. The non-cacheable predictor can be implemented as a direct map, an N-way associative cache, or a fully associative cache.
Abstract: A processor includes a time counter and a time-resource matrix and provides a method for statically dispatching instructions if the resources are available based on data stored in the time-resource matrix, and wherein execution times for the instructions use a time count from the time counter to specify when the instructions may be provided to an execution pipeline. The execution times are based on fixed latency times of instructions with exception of the load instruction which is based on the data cache hit latency time. A data cache miss causes the load instruction and subsequent dependent instructions to be statically replayed at a later time using the same time count.
Abstract: A processor includes a time counter and provides a method for statically dispatching fused instructions with first operation and second operation with preset execution times for forwarding of result data from the first operation to the second operation without writing to a register, and where the preset execution times are based on a time count from the time counter provided to an execution pipeline.
Abstract: A processor includes a time counter and a register scoreboard and operates to statically dispatch instructions with preset execution times based on a write time of a register in the register scoreboard and a time count of the time counter provided to an execution pipeline.

Abstract: A multithread processor includes a time counter and a register scoreboard and provides a method for statically dispatching instructions with preset execution times based on a write time of a register in the register scoreboard and the time counter provided to an execution pipeline.
Abstract: A processor includes a time counter and a time-resource matrix and provides a method for statically dispatching instructions if the resources are available based on data stored in the time-resource matrix, and wherein execution times for the instructions use a time count from the time counter to specify when the instructions may be provided to an execution pipeline.
