• the European and the Asian options of the the Black-Scholes model,
• the European and the European barrier options of the Heston model.

The Black-Scholes model, which was first published by Fischer Black and Myron Scholes in 1973, is a well known basic mathematical model describing the behaviour of investment instruments in financial markets. This model focuses on comparing the Return On Investment for one risky asset, whose price is subject to geometric Brownian motion and one riskless asset with a fixed interest rate.

The geometric Brownian behaviour of the price of the risky asset is described by this stochastic differential equation: where S is the price of the risky asset (usually called stock price), r is the fixed interest rate of the riskless asset, is the volatility of the stock and is a Wiener process.

According to Ito's Lemma, the analytical solution of this stochastic differential equation is as follows: where , (the standard normal distribution).

Entering more specifically into the financial sector operations, two styles of stock transaction options are considered in this implementation of the Black-Scholes model, namely the European vanilla option and Asian option (which is one of the exotic options). Call options and put options are defined reciprocally. Given the basic parameters for an option, namely expiration date and strike price, the call/put payoff price could be estimated as follows. For the European vanilla option, we have: where S is the stock price at the expiration date (estimated by the model above) and K is the strike price. For the Asian option, we have: where T is the time period (between now and the option expiration date) , S is the stock price at the expiration date, and K is the strike price.

The Heston model, which was first published by Steven Heston in 1993, is a more sophisticated mathematical model describing the behaviour of investment instruments in financial markets. This model focuses on comparing the Return On Investment for one risky asset, whose price and volatility are subject to geometric Brownian motion and one riskless asset with a fixed interest rate.

Two styles of stock transaction options are considered in this implementation of the Heston model, namely the European vanilla option and European barrier option (which is one of the exotic options). Call options and put options are defined reciprocally. Given the basic parameters for an option, namely expiration date and strike price, the call/put payoff price can be estimated as discussed in this article.

Examples of usage for the European and Asian options by BlackSchole model:

> blackeuro -b <binary_file_name> [-n number_of_repeat] [-s number_of_simulation] [-k number_of_time_partition] [-c expect_call_price] [-p expect_put_price] 
> blackasian -b <binary_file_name> [-n number_of_repeat] [-s number_of_simulation] [-k number_of_time_partition] [-c expect_call_price] [-p expect_put_price] 

The outputs of both commands are the expected call and put prices. The -b <binary_file_name> option can be used to specify a binary file name different from the default <kernel_name>.hw.xilinx_xil-accel-rd-ku115_4ddr-xpr.awsxclbin

The model parameters are specified in a file called blackEuro.parameters and blackAsian.parameters respectively. The meaning of the parameters is as follows.
