Lock Free Streaming of Executable Code Data

摘要

A disassembler receives instructions and disassembles them into a plurality of separate opcodes. The disassembler creates a table identifying boundaries between each opcode. Each opcode is written to memory in an opcode-by-opcode manner by atomically writing standard blocks of memory. Debug break point opcodes are appended to opcode to create a full block of memory when needed. The block of memory may be thirty-two or sixty-four bits long, for example. Long opcodes may overlap two or more memory blocks. Debug break point opcodes may be appended to a second portion of the long opcode to create a full block of memory. A stream fault interceptor identifies when a requested data page is not available and retrieving the data page.

1. A computer-implemented method, comprising:
receiving instructions comprising a plurality of opcodes, each opcode comprising one or more bytes of data; disassembling the instructions into separate opcodes; creating a table identifying the boundaries between each opcode; and writing each opcode to memory in an opcode-by-opcode manner by atomically writing standard blocks of memory.
