Network functions virtualization platforms with function chaining capabilities

A method comprising:

• providing one or more central processing units (CPUs);
• receiving, from a respective central processing unit (CPU) of the one or more CPUs, a sequence of calls to a field programmable gate array corresponding to a first function and a second function;
• receiving data from the respective CPU;
• providing, via the field programmable gate array, a first hardware accelerator based on stored custom logic data, wherein the first hardware accelerator performs the first function on the data based on a set of conditions and provides corresponding first output data;
• and
• providing, via the field programmable gate array, a second hardware accelerator based on the custom logic data, wherein the second hardware accelerator receives the first output data from the first hardware accelerator, performs the second function on the first output data without routing the first output data external to the field programmable gate array, and provides corresponding second output data.

A tangible, non-transitory, computer-readable medium, having stored thereon program instructions that, upon execution by processing circuitry of a platform system, cause the platform system to perform operations comprising:

• providing access to a central processing unit (CPU);
• receiving, from the CPU, data based on a direct memory access connection;
• providing, via a programmable logic device, a first hardware accelerator to perform a first function on the data based on a set of conditions and to provide corresponding first output data;
• determining that a condition of the set of conditions is met;
• and
• providing, via the programmable logic device, a second hardware accelerator to receive, in response to determining that the condition is met, the first output data from the first hardware accelerator, to perform a second function on the first output data without routing the first output data external to the programmable logic device, and to provide corresponding second output data.
