Tool-level and hardware-level code optimization and respective hardware modification
The present invention relates to a method for compiling high-level software code into hardware, transforming each instruction into a respective hardware block and using an execution control signal representing the program pointer for triggering the execution within each respective hardware block.
1. A method for generating hardware by compiling high-level software code, the method comprising:
grouping, by a system, software instructions into groups, wherein grouping the software instructions includes detecting instruction patterns and sequences in the software instructions;
transforming, by the system, the groups of software instructions into a hardware description language describing respective hardware blocks, wherein the hardware blocks are hardware representations of the respective groups of software instructions and provide one or more hardware functions for one or more target algorithms described by the groups of software instructions; and
generating, by the system, a main module interconnecting and controlling the hardware blocks,
wherein the main module includes:
i) a register file configured to store data received from the hardware blocks, and
ii) a decoder configured to select, for each currently active hardware block, a next hardware block to become active based on pointer information received from the currently active hardware block, and
wherein each of the hardware blocks is configured to:
receive input data from the register file,
transmit result data to the register file, and
generate the pointer information for the main module.
2. The method according to claim 1 , wherein the hardware blocks are combined into hardware modules, the hardware modules comprising registers.
3. The method according to claim 2 , wherein the main module uses input multiplexers in front of each hardware module to select the source of the input data according to received execution control signals.
4. The method according to claim 1 , wherein a last instruction implemented in at least one of the hardware blocks is used to generate the pointer information, wherein the last instruction is a jump operation or call operation.
5. The method according to claim 1 , wherein the groups of software instructions are transformed into synthesizable code in the hardware description language.
6. The method according to claim 1 , wherein the groups of software instructions are transformed into a gate netlist in the hardware description language.
7. The method according to claim 1 , wherein the hardware blocks are interconnected based on an order of execution of the software instructions represented in the hardware blocks.
8. The method according to claim 1 , wherein the software instructions do not specify the hardware blocks and interconnection of the hardware blocks.
