Detailed Description

template<typename DataType, unsigned int CapacityInBytes, unsigned int NumInputs, unsigned int NumBanks, unsigned int InputQueueLen>
class ArbitratedScratchpad< DataType, CapacityInBytes, NumInputs, NumBanks, InputQueueLen >

Scratchpad Memories with arbitration and queuing.

Template Parameters

DataType	DataType if input and output
CapacityInBytes	Capacity of scratchpad
NumInputs	Number of Inputs
NumBanks	Number of Banks
LenInputBuffer	Length of Input Buffer
LenOutputBuffer	Length of Output Buffer

A Simple Example

#include <ArbitratedScratchpad.h>
 
...
ArbitratedScratchpad<DataType, ScratchpadCapacity, NumInputs, NumBanks, InputQueueLength> dut;
dut.reset(); // optional in this case, suitable if xbar is a class member rather than local variable
...
dut.load_store(curr_cli_req, curr_cli_rsp, ready);
...
