Abstract

Apparatus and methods are disclosed for implementing block-based processors including field programmable gate-array implementations. In one example of the disclosed technology, a block-based processorincludes an instruction decoder configured to generate decoded ready dependencies for a transactional block of instructions, where each of the instructions is associated with a different instructionidentifier encoded in the transactional block. The processor further includes an instruction scheduler configured to issue an instruction from the set of transactional block of instructions out of order. The instruction is issued based on determining that decoded ready state dependencies for an instruction are satisfied. The determining includes accessing storage with the decoded ready dependencies indexed with a respective instruction identifier that is encoded in the transactional block of instructions.

Description

Background technique [0001] Due to the continued transistor scaling predicted by Moore's Law, microprocessors have benefited from continued increases in transistor count, integrated circuit cost, manufacturing capital, clock frequency, and energy efficiency, while the associated processor instruction set The architecture (ISA) has changed very little. However, the benefits realized from the lithographic scaling that has driven the semiconductor industry for the past 40 years are slowing or even reversing. The Reduced Instruction Set Computing (RISC) architecture has been the dominant paradigm in processor design for many years. Out-of-order superscalar implementations have not shown consistent improvements in area or performance. Therefore, there is ample opportunity for improvements in processor ISAs to scale performance improvements. Contents of the invention [0002] Methods, apparatus, and computer-readable storage devices for configuring, manipulating, and compiling ...
