High level synthesis (HLS) refers to an automated process that creates a digital hardware from an algorithmic description of some computation. From the perspective of Smalltalk, this process consists of converting code from the oriented object level to the register transfer level (RTL), that supports direct compilation to the hardware level. In this paper, we present first s teps t o a chieve t his process. We introduce a Smalltalk-based meta-model that allows expressing descriptions (i.e.

A such circuit description can be run on top of the Smalltalk VM, simulating the parallelism intrinsic of hardware. Alternatively, it can be compiled into a binary representation directly transferable to FPGA chips, which can run and exchange data with Smalltalk objects.
