“…Fabric is a medium that keeps track of the number of tokens available at each device target [5]. When OCCA (Master) send a request to Main Memory (Target), if the amount of token is sufficient, Fabric will send a grant signal to OCCA [3][5] [6]. Only then would the OCCA get the permit to send command and data to Main Memory.…”

“…3, the signals on the interface consist of separate sets of signals for control, command and data [5] [6]. Base on the interface, OCCA support memory read/ write and configuration read/write transactions to CPU and main memory space [5] [6].…”

“…The master interface of OCCA consists of control, command and data signals that provide information to the Fabric or internal module for flow control on the master interface, and arbitration and decode of the transaction [5] [6]. On the other hand, target interface of OCCA also has a control, command, data interface that carries flow-control and decode between the Fabric and the HA internal module interface.…”

Modular Hardware Accelerator (HA) is designed for acceleration purpose which assists CPU (Central Processing Unit) in handling specific task. Modular HA capable to manage multiple engine and communicate them with core processor and main memory through the standard system on-chip (SoC) fabric architecture. The modules of modular HA are Scheduler, Storage, Workload Generator, On-Chip Communication Adapter (OCCA) and Power Management Unit (PMU). OCCA designed to be compliant to the SoC fabric architecture standard and plays an important role in the transaction and handshaking protocol with the Fabric. It responsible for communication behavior such as interface instantiation, arbitration, flow control, address and command signal decode capability, error handling, and power management function. In order to reduce the time of architecture design future usage, OCCA module has the block of reusable architecture. Furthermore, OCCA has a simple parameterize capability let the designer easy work with the different bits of control signal, command signal and data. With all the functionality of OCCA, some debug tool such as VCS and Assertion Based Verification (ABV) use for verification and simulation purpose to ensure get a correct result.
