A New Compiler for Space-Time Scheduling of ILP Processors

Rajendra Kumar and P. K. Singh

Abstract—the exploitation of potential performance of superscalar processors has shown that processor is fed with sufficient instruction bandwidth. The fetcher and the Instruction Stream Buffer (ISB) are the key elements to achieve this target. Beyond the basic blocks, the instruction stream is not supported by current ISBs. The split line instruction problem depreciates this situation for x86 processors. With the implementation of Line Weighted Branch Target Buffer (LWBTB), the advance branch information and reassembling of cache lines can be predicted by the ISB. The code generation for parallel register share architecture involves some issues that are not present in sequential code compilation and is inherently complex. To resolve such issues, a consistency contract between the code and the machine can be defined and a compiler is required to preserve the contract during the transformation of code. We want to achieve high level parallelism at faster clock speed it require distribution of processor resource and avoiding primitive that require single cycle global communication. Distribution of its resources, including instruction stream, register files, memory port and ALUs, over a pipelined two dimensional mesh interconnect are done by raw microprocessor [4]. In this paper, we propose a compiler RPCC for general purpose sequential programs on the raw machine.
